Message from the Chief Guest

Modern healthcare is deeply indebted to Medical Physics for its different discoveries and innovations based on which almost all aspects of diagnosis, therapy and rehabilitation have seen a significant improvement in the last century, starting from discovery of X-ray and the Electro Cardiogram.

In Bangladesh many of the latest technologies in medicine have started to be available in the recent times. However, because of

the high cost of imported equipments and lack of maintenance and repair, the services are proving to be beyond the affordability of the majority of our population, particularly the rural population. There is acute shortage of qualified manpower for proper utilization and maintenance of medical equipments. This situation is giving rise to premature failures of the equipments and a huge waste of national resources.

The solution lies in two parallel approaches, to train and employ manpower like Medical Physicists and Biomedical Engineers at all hospitals, and to develop such equipments locally through acquisition, improvisation and innovation of technology. I am happy that Bangladesh Medical Physics Association (BMPA) and the Postgraduate Department of Biomedical Physics & Technology of Dhaka University have made considerable progress in this regard. I know that some equipments developed by them are working satisfactorily in different hospitals in our country for more than a decade.

I came to know that the Department, with funding from a private corporate body, is developing a package of personal computer (PC) based health monitoring and diagnosis for the rural health centres where we have already provided internet connection. This eventually may be transformed to a nationwide telemedicine network. This is very encouraging and we wish them all success.

I am delighted to know that BMPA and the Department of Biomedical Physics & Technology of Dhaka University have jointly organized a Regional Conference on Medical Physics and also a day long Exhibition to show medical equipments and new techniques developed by our scientists. The conference and the exhibition are very timely and match the theme of ‘Digital Bangladesh’ announced by the present Government. I wish this conference and exhibition a grand success.

Message from the Vice Chancellor, Dhaka University, Special Guest

The Department of Biomedical Physics & Technology of the University of Dhaka held an exhibition on the occasion of the University day last year and I was impressed by the research and development being carried out there by our young scientists under the leadership of Professor K Siddique-e Rabbani. The thing that particularly caught my eyes is that this department is trying to improvise and innovate new methods and technologies suited to the rural environment in countries like ours. In spite of tremendous progress of science and technology, the common people in countries

like ours have remained to be deprived of the services of modern health care technology. Although we can see traces in the capital city and in some of the large districts, the services are not within the means of the majority of the country. The scenario would be the same in any low and medium income country of the world I believe. Therefore, the philosophy of developing indigenous capacity in technology by the visionaries in this department is commendable, and I believe this department is playing its role in fulfilling the dream of our people with which Dhaka University was established in 1921.

It is also encouraging to know that scientists in UK, USA, Australia, Korea and Singapore have already started working on techniques and methodologies innovated by this department, and a sophisticated medical equipment designed and developed by people belonging to this group is working with satisfaction in a hospital in a neighbouring country for about a year. Within the country a number of medical equipment made by them are being used by hospitals, clinics, and by patients for about two decades. I think these efforts should be supported and promoted by the Government; to see if our local hospitals could be equipped with medical appliances developed by our local scientists and technologists.

We also need trained Medical Physicists to understand the inner details while procuring modern medical equipment from abroad, to install and utilize these properly, to maintain, and repair such equipment. Since the country still lacks a policy to this effect, expensive medical appliances imported at huge costs to the nation are lying idle, or are being used rarely, or are left to be thrown away after something goes out of order. This calls for employing Medical Physicists and Biomedical Engineers in all major hospitals. Therefore, the conference and exhibition being orgainsed by the Bangladesh Medical Physics Association and the Department of Biomedical Physics & Technology of the University of Dhaka is very timely, and I feel proud that Dhaka University could be a part of this endeavour. I wish this conference and exhibition all success.

Welcome Address & Message from Professor Barry Allen, Special Guest

Professor AFM Ruhal Haque, Hon Minister for Health and Family Welfare Prof Siddique-e Rabani, Conference Chair Prof AAAMS Arefin Siddique, Hon Vice-Chancellor, University of Dhaka, Members of the Organising Committee and Honored Colleagues, The International Union for Physics and Engineers in Medicine (IUPESM) comprises the International Organisation for Medical Physics (IOMP) and International Federation of Medical and Biological Engineers (IFMBE) as affiliate organizations. The IOMP comprises 80 adhering national organizations representing 16500 MPs worldwide; the IFMBE has some 24 000 members.

Our objective is to facilitate the role of medical physics and engineering throughout the world, with particular emphasis on the developing countries. To this end we embarked on a number of new initiatives since the world congress in Seoul in 2006, during my term as President, IOMP and President Elect, IUPESM.

Autonomous regional chapters of the IOMP are an important part of its operations. The first such organization was EFOMP in 1980, which has long served the requirements of medical physicists in Europe, then ALFIM (or LAMPA in English) in Latin America in 1984, SEAFOMP in SE Asia and AFOMP in the Asia-Pacific region in 2000. Under guidance and support of the IOMP, new regional societies have recently formed in the middle-east (MEFOMP) and Africa (FAMPO). Such institutions are essential if the health sciences in developing countries with language barriers, restricted funds and travel budgets are to thrive. Bangladesh is a member of AFOMP and should plan to hold it annual medical physics meeting in the near future.

An important role of the IUPESM is to support the development and implementation of appropriate medical devices in developing countries. I proposed and was the inaugural chair of the Health Technology Task Group (HTTG), an initiative that was adopted unanimously by IUPESM at WC2006 in Seoul. This task group seeks to apply our skills in medical physics and biomedical engineering to evaluate and obtain solutions for improved health management in the developing countries. I believe that HTTG should play an important role in facilitating the development and implementation of health technologies in Bangladesh.

Message from the President, IOMP

Welcome to the Regional Conference on

Medical Physics 2011

Hosted by the Bangladesh Medical Physics Association and the

Dept of Biomedical Physics & Technology, University of Dhaka

I am delighted to welcome all delegates attending the Regional Conference on Medical

Physics at Dhaka University, and it is my privilege to particularly thank the Bangladesh

Medical Physics Association as one of the younger members of the IOMP family to host this

meeting and by this to match the key elements of the IOMP mission: (i) advancing Medical

Physics in science, (ii) fostering the educational and professional development of medical

physicists, and (iii) disseminating Medical Physics knowledge and expertise, particularly in

developing areas.

Medical Physics today has gained significant attention in the science community and in the

public. Medical Physicists – IOMP represents currently more than 18,000 professionals - are

doing much more than just dealing with clinical application of ionizing radiation in a hospital.

Medical Physics is expanding more and more, and today nearly all branches in health care

are benefiting from the inventions and expertise of medical physicists. Medical Physics is a

janus-faced science, rooting in physics and looking at the patient, i.e. the scientific

creativity of the medical physicist is driven by the suffering patient. This governs the

uniqueness of our profession, being interdisciplinary and always committed to highest

professional and ethical standards.

A scientific meeting like your Regional Conference on Medical Physics in Dhaka is a perfect

platform to advance Medical physics by exchanging new ideas, and to offer training

7

opportunities and to disseminate knowledge and expertise by bringing together teachers

and students. Globally, there is yet a significant disparity in the status of health care, and

medical physicists are particularly challenged to cope with that divergence. IOMP

acknowledges your efforts when dedicating a session on this specific subject. The

importance of health care in rural areas is obvious, for instance the majority of the ca. 8 Mio

patients dying of cancer each year was living in countries with poor health care

opportunities. That “Cancer Crisis” as coined by IAEA & WHO requires also answers from the

community of Medical Physicists and challenges for the development of suitable

instrumentation, e.g. affordable imaging and investigation methods, appropriate treatment

equipment including adapted communication and energy technologies. The IOMP partnering

with the International Federation for Medical and Biological Engineering (IFMBE) under the

umbrella of the International Union for Physical and Engineering Sciences in Medicine

(IUPESM) initiated the IUPESM Health Technology Task Group (HTTG) which aims to define

the health care technology requirements in low and medium income countries and to

provide support in developing their health care systems as related to medical physics and

engineering. New ideas emanating from your meeting will certainly stimulate the IUPESM

HTTG and corresponding initiatives launched by the WHO, the IAEA and other organizations

to promote medical physics in your region and by this to provide best service to the ever

increasing number of patients.

Let me wish all delegates a successful, inspiring and considering your wonderful venue an

enjoyable meeting in Dhaka.

Message from the Secretary of Health & FW, GOB

I am glad to know that Bangladesh Medical Physics Association and the Department of Biomedical Physics & Technology of Dhaka University have organized a Regional Conference on Medical Physics. This is very timely as modern healthcare depends greatly on technology coming from Physics and related Engineering, and without their active participation we cannot take the fruits of such development to the common people in the

country. I understand in a limited scale, Medical Physicists and Biomedical Engineers have started contributing in this area in the recent times specially in some hospitals run by private enterprises and NGO’s. It may be equally relevant for the Government run hospitals too. Modern medical equipment are very costly and very expensive to maintain and repair as they mostly come from countries with high wages. If such devices could be designed, developed and manufactured locally, the prices could come down drastically, and service could also be ensured through local maintenance and repair. I understand that the people at the Department of Biomedical Physics & Technology of the University of Dhaka started their research about three decades back with this vision and they have already attained a level of expertise and confidence to take up such a challenge. I hope there will be scopes in the near future to sit together and discuss how their developments could be transferred to the local hospitals and clinics. I wish all the best and success to the Regional Conference of Medical Physics.

I feel honored to be invited to write a message for the Regional Conference on Medical Physics to be held at Dhaka on 18 February 2011. The initial contact of Medical Physics with this country happened in the early 1960s when late M Shamsul Islam having finished his work at Leeds University for PhD degree in the area of Cosmic Radiation was employed briefly as Hospital Physicist at a Leeds hospital. However back in Dhaka, M Shamsul Islam joined the Department of Physics, University of Dhaka, and developed the area of research on Experimental Cosmic Radiation in the department.

Research on Biomedical Physics in this country happened through a chance occasion when I was working at the Industrial Physics Division, Bangladesh Council of Scientific & Industrial Research (BCSIR) Laboratories, Dhaka. I was watching the US serial 'Science Reports' on Bangladesh TV in late 1978 demonstrating the work of Dr C Bassett at the New York Presbyterian Hospital on the augmentation of bone repair by inductively coupled electromagnetic fields. It so happened that in those days I was routinely visiting my father receiving treatment of fractured femur as inpatient at the Rehabilitation Institute & Hospital for Disabled(RIHD), Dhaka & I had the chance to discuss the above matter of the TV serial with the Director, late Dr R Garst on one occasion of his going rounds in the ward. Dr Garst took immediate high interest in the matter and thus followed the very unique multi-institutional & grand collaboration of research to develop the method between the Industrial Physics Division, BCSIR Laboratories, Dhaka, the Department of Physics, University of Dhaka, the RIHD(presently renamed Orthopedic Hospital & Rehabilitation Institute) for clinical human trials, the Food Science & Technology Division, BCSIR Laboratories, Dhaka and the Department of Pathology, Institute of Postgraduate Medicine & Research(presently renamed Bangabandhu Sheikh Mujib Medical University (BSMMU). Funding came from the Bangladesh Medical Research Council to meet certain sundry expenses. At the Department of Physics, University of Dhaka, M Shamsul Islam with his background of ex-Hospital Physicist formed the group with the freshly joined Khondkar S Rabbani with background of PhD in the area of Solid State Electronics. The group has emerged as the new discipline of Biomedical Physics & Technology as the youngest daughter of the Department(adding to the departments of Applied Physics, Electronics & Communication Engineering, Theoretical Physics, and Computer Science & Engineering), to meet the human resources needs in the area along with Gono Bishwabiddalay, Savar, Dhaka. I understand that the present activities of new Department at the University of Dhaka are presently focused toward postgraduate studies & research on body's electrical impedance, nerve conduction, solar water disinfection, etc.

I wish the Conference all success.

Message from Conference Chair

After completing my PhD in microelectronics in 1978 in UK under a Commonwealth scholarship I decided not to continue in this field as I believed that we cannot put an IC chip in the market from Bangladesh in the next two decades. I realized that without indigenous development of technology our nation cannot prosper, and I felt an inner urge to make my life useful to the society which nurtured me from my birth. I had no job back home, and in spite of lucrative offers from abroad, decided to come home straight and try my luck. Professor Muhtasham Hussain, the then Chairman of the department of Physics of Dhaka University said, “I like your subject, if you do not get anything else in Dhaka, I’ll take you”. So he took me as an Assistant Professor on an adhoc basis (which was allowed at that time) and that’s how my fate got its one important milestone. I was wondering around to look for an avenue which was well suited to our country’s needs. With Professor Hussain and Prfessor A K M Siddiq, I started doing research on Solar and Wind energy, designed and fabricated solar water heaters, wind mills etc. I had a hobby of designing and fabricating electronic circuitry and one fine morning Dr. M Shamsul Islam of the department of Physics called me and asked for my help with modern transistor based electronics for a research project on bone fracture healing using electromagnetic fields, which he and his childhood friend Dr. A Sattar Syed of BCSIR had been trying using older valve based electronics. Dr. Syed explained the requirements and I designed a simple low cost circuit which was used successfully on human subjects at the Hospital for disabled (Pongu Hospital) for about two years, and we had a good outcome of the research project, with active support of Dr. Salek Talukder and his team there. After this success I was approached by Professor AFM Ruhal Haque of the Hospital for Disabled (now the Minister for Health and Family Welfare, and the Chief Guest of this ceremony) to devise a portable electrical bone healing unit for a patient of his, which I did. Professor Shamsul Islam motivated me to give more time to this field and gradually I became the key research person for Medical Physics in the department.

Jointly we started to offer Masters thesis to students in 1981. In 1983 through a sheer chance Professor B H brown of Sheffield University came to Dhaka to give an invited talk on Biomedical Physics where Professor Islam also presented a paper on the local bone fracture healing work. This led to an academic link with Sheffield sponsored by British Overseas Development Agency, meant for three years, but eventually continuing to 10 years seeing the success of the local group. With the help of Sheffield we were able to organize a Master’s course on Biophysics and Medical Physics in 1984. An informal link with Sheffield still continues to this day.

Sheffield gave us a real exposure to modern methods in Medical Physics having a broad span of activities. In deciding which areas to go for research, I had two intuitive feelings. First, we should go for areas involving electricity where the instrumentation needed can be designed and fabricated locally by us. I believed that doing research based on sophisticated technology and expensive appliances coming from the West, which was the order of the day in Third World countries, we cannot go far. Secondly, for research, we should not take up problems which the West with their advanced expertise, facilities and experience, are finding hard to crack. Besides, I also thought that we need to reproduce, by acquiring technology, essential equipment locally, otherwise our people will not be able to get the benefits of modern

technology. For the latter I chose computer based instrumentation for Nerve conduction measurement, and with the help of the Sheffield scientists, we built a full system locally in 1988, involving both hardware and software. Using this I started giving routine clinical service in Bangladesh in the same year and got patients referred to by eminent neurologists of the country, and which is still being used at a local hospital. Here I should specially mention the support of Professor Rashid Uddin Ahmed, Professor M A Mannan and Late Professor M Ibrahim of BIRDEM. The development of computerised equipment, and offering routine clinical service in nerve conduction in 1988 – were both firsts in Bangladesh and a photograph of this equipment is given below.

For research, I chose Electrical Impedance measurements, in which Professor Brown had a pioneering contribution in the form of Electrical Impedance Tomography (EIT), similar in concept to the more widely used Computed X-ray Tomography. We had a gift of this equipment with a generous support of the British Council and did some valuable work. However, this led to our own innovation of Focused Impedance Method (FIM), offering localized investigation but at much less sophistication. Already Universities in UK, and Korea have started using this method, we are developing an FIM unit to be incorporated into a project of an Australian University, and a couple of R&D organizations in Switzerland and USA have shown interest. We feel that FIM has the potential of becoming a choice method for investigation of many diseases and disorders including certain cancers.

Our routine work on Nerve conduction revealed some limitations of existing techniques and this led us innovate a new method, which we named Distribution of F-Latency (DFL); this also seems to hold great potential in improving the diagnosis, and could be the first choice in any investigation of peripheral nerves. Scientists in UK and Singapore have already started work on our method.

Our work on destruction of diarrhoeal germs in drinking water has led to a successful low cost method utilizing solar energy for household use in the rural areas, side by side with improved rainwater collection. Since surface water does not have arsenic, this method can also become a solution for the arsenic menace indirectly.

We have been making an Iontophoresis equipment for the treatment of excessive sweating of palms and soles, a muscle and nerve stimulator for physiotherapy for more than a decade for hospitals, clinics and patients in Bangladesh, Recently we made a computerized equipment for dynamic foot pressure measurement for a Diabetic hospital in Karachi, Pakistan, and it is being used for routine clinical investigation for more than a year now with satisfaction. We are also developing several other equipment like ECG, EEG, SpO2, devices to aid the blind and the profoundly deaf, a low cost device to determine bone degeneration (osteoporosis) using existing X-ray equipment, artificial hand and leg prosthesis that will offer limited functionality through muscle signals generated by the will of the user. Recently we have taken up a programme to develop a personal computer based diagnostic package including temperature, respiration, ECG, heart rate, etc., that can be integrated to a nationwide internet connected computer network already developed by the Ministry of Health and Family Welfare. This can also lead to telemedicine, and all this could be done at a fraction of the cost of any imported equipment, giving much longer useful life too.

At different phases of our work we got financial supports from the World Health Organisation, the Asiatic Society, University Grants Commission, Bose Centre of Dhaka University, Ministry of Science & Technology and Ministry of Education. Uppsala University of Sweden has already sanctioned a fund for our department this year. Recently the Farm Fresh wing of Akij Food and Beverage Ltd., a private corporate body, has come up with financial support for the development of a number of the above items. They are also the main sponsor of this conference and exhibition. Normally private corporations fund events that bring a great deal of media publicity which does not happen in the funding of scientific and technology research. Therefore this gesture is a commendable and pioneering one, and this group definitely deserves our warm thanks and felicitations.

13

My message has become a history of some sort, but I felt it necessary to generate enthusiasm and self confidence among our young scientists, who are my main target. My message to them would be to start at a low level, persevere, and build up as one goes along. This will give the real strength and confidence in technology. All around us there is an atmosphere of glamour, which has also spread into science and technology research. For example, we have spent millions of dollars for high sounding arsenic mitigation research but no real solution has gone to the common people so far. Therefore, we need to be careful not to get trapped in such glittering avenues, as we have only one life to make use of. We need to remember that millions of our fellow countrymen have sacrificed their food, their living comfort to fund our education, to fund our research. Unless we direct our research to the alleviation of their miseries at this moment, we shall be answerable to our own conscience. We can play around with high sounding science and technology only after we achieve the minimum of the above target.

We have tried our best to organize this conference and exhibition in a befitting manner, however our inexperience will definitely show up here and there, and I, on behalf of the whole organizing committee, ask for forgiveness and constructive criticisms for the future.

Message from the General Secretary

It gives me a great pleasure to welcome you all to the regional conference on Medical Physics in Dhaka, to be held on 18th February, 2011, jointly organized by Bangladesh Medical Physics Association (BMPA) and Department of Biomedical Physics and Technology (BMPT), University of Dhaka.

The history of Bangladesh Medical Physics Association is quite recent and it started its journey in 1998 under the able leadership of Dr. Gias Uddin Ahmad, the then Professor of Physics in Bangladesh University of Engineering and Technology (BUET). The Department of Biomedical Physics and Technology of University of Dhaka was established very recently in November 2008 under the leadership of Professor K S Rabbani as the founder chairman.

Although, Medical Physics is meant for cancer diagnosis and treatment, we (BMPA & BMPT) believe that the Medical Physics term should include all aspects of Physics and Engineering in Medicine and Health Care. We also visualize that poor and under privileged population especially in rural areas of developing countries like Bangladesh, should get the benefit of technological advancement in Medicine and Health Care through the development of low-cost sustainable innovative devices and systems. In line with this vision this regional conference has the taste and diversity of different fields of Physics and Engineering in health care in addition to traditional Radiation Physics.

I understand that many Medical Physicists, Physicians, Radiation Oncologists, Physicists and Nuclear Medicine Specialists, Engineers, and a large number of students from Physics and Applied Physics disciplines are going to participate in this Conference. We are encouraged and inspired by their sheer number and enthusiasms in this emerging and challenging area.

I wish the Regional Conference on Medical Physics much success.

HOMAGE TO LATE PROFESSOR M SHAMSUL ISLAM

1 January, 1929 – 6 April, 2005

Late Professor M Shamsul Islam was the visionary who understood the future importance of Medical Physics and Biophysics at a time when many stalwarts of Physics in the country were doubtful about its significance. Although he did his Ph.D. in Cosmic Ray Physics and established a laboratory in the early sixties after his return, the attraction to Medical Physics was in the back of his mind in which he engaged himself briefly in Leeds, UK in the early sixties. Therefore as soon as his childhood friend Dr A Sattar Syed asked for his help in a project to develop and study bone healing through electrical stimulation in 1978 he responded enthusiastically, and also motivated the fresh Ph.D. returnee Dr. K Siddique-e Rabbani in joining the group. With the success of the initial research project Professor Islam realized the need to involve students in this area of research, and to offer formal courses. Thus students could take thesis work in Medical Physics as part of their M.Sc. degree since 1981. Professor Islam supervised scores M.Sc. thesis students from then on till his retirement, jointly with Dr. Rabbani. He also organized academic link programmes with Sheffield for Medical Physics and with Oxford for Biophysics in 1983 when a course on Biophysics & Medical Physics was initiated in the M.Sc. curriculum. The Sheffield link was jointly co-ordinated on the other side by Professor B H Brown, an innovative scientist and pioneer of Electrical Impedance Tomography (EIT). This link was very significant in giving necessary exposure and boost to the research of the group. With Prof Islam’s initiative the group could obtain funding, together with the prestigious diabetic centre BIRDEM, from World Health Organisation on a new project involving Bone resonance to determine Osteoporosis, which also got enthusiastic support from the legendary Professor M Ibrahim, the founder of BIRDEM. He also got his wife, Professor Quamrun Nesa Begum, an outstanding Professor of Physics in her own right, to dedicate some of her time to Medical Physics research, and she contributed significantly as well.

Without the vision and initiative of Professor M S Islam it is difficult to guess if the department of Biomedical Physics & Technology could ever come into existence, and if the current state of research could have been achieved. Let his soul rest in eternal peace.

Abstract: A growing body of evidence suggests that a preclinical phase of Alzheimer’s disease (AD) exists several years or more prior to the overt manifestation of clinical symptoms and is characterized by subtle neuropsychological and brain changes. Identification of individuals prior to the development of significant clinical symptoms is imperative in order to have the greatest treatment impact by maintaining cognitive abilities and preserving quality of life. Functional magnetic resonance imaging (fMRI) offers considerable promise as a non-invasive tool for detecting morphological brain changes in Alzheimer disease affected patients. In fact, evidence to date indicates that functional brain decline precedes structural decline in preclinical samples. Therefore, fMRI may offer the unique ability to capture the dynamic state of change in the degenerating brain. This analysis examines morphological change in brain structure in those at risk for AD as well as in early AD. Analysis of fMRI data and findings is done on at-risk groups by collecting data from fMRI data centre which is gathered according to the virtue of genetic susceptibility or mild cognitive decline followed by an appraisal of the methodological issues concerning the diagnostic usefulness of fMRI in early AD. Data for Alzheimer disease affected subjects were obtained from fMRI data centre and analyzed in this paper. The analysis result shows that the cortex, hippocampus, and ventricle area of the Alzheimer diseased patient have shrunk dramatically than the normal subject and other changes of brain are distinguishable. A discussion of data analyzing procedure has been given that will improve the ability to reliably detect early brain changes and will help for early identification of Alzheimer (AD) disease and to cure the disease.

Abstract: Human generate both visual and auditory phonetic signals by talking and movements of lips. When someone is talking face to face, perceiver typically integrates phonetic distinctiveness of both the visual and auditory stimuli (audiovisual integration).The prominent function of the brain’s audio-visual response is to enable the evaluation of novel, environmental events in order to prepare for potential action. This analyses reveal neuroanatomical and neuroimaging studies pertaining to audio-visual effect and particular emphasis will be given to neuroimaging studies using functional magnetic resonance imaging(fMRI). Analyses of haemodynamic responses and audio-visual effects have been done on neuroimaging data. These approaches provide complete information as they evaluate different features of audio-visual effect. fMRI data analysis has been accomplished by using a validated set of neuroimaging tools from the FMRIB Software Library (Version 4.1.5, FSL) used by Department of Clinical Neurology, University of Oxford. Neuroimaging studies suggest that auditory and visual shows quite similar patterns of brain activation. We observed that regions of the FEFs, PPC, and SMA were significantly modulated by spatial cues. Additionally, areas of the auditory cortex are also activated for this contrast, possibly indicating preparatory biasing in sensory cortices. We found quite similar regions involved in visuospatial orienting.

Abstract: Public health and safety always raise national economic concerns in developing countries like Bangladesh when catastrophic disasters causing unavoidable medical emergencies become a “lost-control”. Careful review can minimize some of the major issues and also by developing better technologies can keep the causing factors under control at pre- and post-disaster stages. Nano-power electronics is an area of emerging semiconductor VLSI technology where scaled down CMOS circuits are primarily used in this project. Scalable design techniques of MOSIS are used for designing a fabricable CMOS integrated chip (IC). A sense amplifier is redesigned to improve specific functions and also lower the power to nano-watts level i.e. 7.15E-03watts to 1.31E-09watts. Floor plan of all components and their pin-assignments of the CAD layout of the test chip are described. PSPICE simulation for verifying operations and power consumption of components in the chip is presented in this paper. Applications of this IC have been explored and it is found to be a life-saving design for ferries, launches, boats etc. in Bangladesh waterways. Application of three types of sensors and their proper placements is identified for this IC such that they can sense the catastrophic situations ahead of time. This IC can also accurately determine the increasing levels of leaking water in the hull and degradation of floating conditions to buoyancy. This low power electronics can be operated by sustainable energy systems when the generator and the primary power source are obvious to fail while sinking. A sequence of preventive functions are generated by the IC that include warnings to captain if a possibility of structural damage, activate the alarm system prior to leaving dock if serious defects detected such as overloading conditions, activate the inflation of floating devices and assure passengers’ away from sinking vehicle, continue power to medical equipments and air supply to patients by auto-control electronic system. Detailed description of such system, sensor logical functions, applicable analysis of physics and thus forming its electronic operational plans are presented in this paper.

Abstract: Nowadays, Optical resonator has generated wide interests in the detection and sensing field. This is possible only for a small change on the refractive index can be detected from the shift of resonance wavelength and the splitting of the resonance modes. The synergy between microresonator and nanoparticle can be used for various applications, such as biological imaging, fluorescent markers for biological processes, contrast agents in bio molecule sensing, cancer therapies and photothermal tumor ablation etc. We experimentally demonstrate a high-Q silicon microring resonator operating at wavelength of 1.55µm with/without Au nanoparticles. We consider the micro ring resonator (4µm in diameter) and the ring waveguide (width is 200nm) as a single mode waveguide. SiO2 as the bottom cladding and air as the top cladding. The two bus waveguides are evanescently coupled to the micro ring

28

resonator, with the coupling gap 100nm and the thickness of the ring resonator and bus waveguide is 250nm. We used 2D Finite Difference Time Domain (FDTD) method & Perfect Matched Layer (PML) as absorbing boundary condition. The Au nanoparticle was placed at the outside edge of the micro ring resonator and found resonance wavelength shift and broadening of the splitting bandwidth with the increase number & size of Au nanoparticles but irrespective of position up to certain limit – when the interaction between metallic nanoparticles and micro ring resonator is becoming so strong that they completely degrade the resonance – the Q is strongly degraded and the intensity at output port is approaching zero. This unique result by Au nanoparticles is used extensively for sensing and nano medicine field.

05. ANALYSIS AND DESIGN OF A HYPOTHERMIA BED

Abstract: A device, hypothermia bed has been designed which is actually a water circulated close loop system with precise control to ensure medical safety. It is designed on the basis of thermo-fluid analysis to provide required amount of heat which is lost from hypothermic patient’s body, when patient’s body temperature goes below 36o Celsius. Here, water is electrically heated up to required temperature and circulated though the copper channel continuously. Required temperature of water depends and varies with patient’s core body temperature. In order to reduce the complicacy arises for controlling mass flow rate through the system, a fixed mass flow rate is chosen for this close loop system. It is especially for the use of intensive care unit, post operative cases and during operation.

Abstract: The design of this prosthesis is for a functional replacement of a natural hand, for subjects with a hand severed from the wrist. A three dimensional model of a mechanical structure of the prosthetic hand has been designed using AutoCAD, a computer aided design software. For the primary model, two basic function of hand, grasping and holding light objects was to be performed by contraction and tension of flexible wires, which acts in a way similar to that of tendons in the fingers. These wires will perform the flexion (grip closing) and extension (grip loosening) actions through the two directions of rotation of a dc motor. The power applied to the motor will be controlled by electrical signals picked up from the muscles (Electromyograph – EMG) of the existing portion of upper limb. The EMG signals will be analysed to obtain mainly the control signals for the direction of rotation of the motor. However, the possibility to use the strength of the EMG signals will also be explored. This artificial musculoskeletal model has been designed using a light material like aluminium in mind. However, due to limitations in fabricating facilities, prototypes are being made using brass. The prosthetic hand can be made available at a low cost without sacrificing its quality of action, and will contribute greatly to the sufferings of a large number of people who have lost their hands.

Abstract: Over the past few years prosthetic legs have become much improved and complex. However their costs are very high and are not within the reach of most people in the Third World. Low-cost fixed prostheses made of wood or plastics are available in some Third world countries, but these offer very basic movement with unnatural gait; climbing stairs gets quite difficult. The prosthesis being worked upon in the present work are for amputees with legs removed above the knee, and would offer a limited rotational movement of the knee joint under voluntary control of the wearer, driven by the EMG signals extracted from thigh muscles. The aim is to make it at a low cost, may be at a cost slightly higher than the passive ones, but allowing a better gait in walking, and in climbing stairs. An initial work was done in this direction by our extended group earlier; the present work gives further improvements. This involves redesigning of the motor and the gear system and that of the electronic circuitry for processing the EMG signals extracted from thigh muscles, interfacing the output to the microcontroller, rotating the motor in two directions thereby accomplishing the movement of the knee joint. The motor, geared down, is mounted horizontally and a pulley system drives the artificial knee joint. A wooden prototype was used to study the motion of the mechanical structure and the action of the motor. Further challenge is to incorporate lighter and stronger material like carbon fibre and testing the prosthesis with an amputee before making it commercially available.

Abstract: Dynamic foot pressure measurement is necessary particularly for diabetic patients, who lack sensation in the feet, to prevent ulcers, eventually leading to gangrene and amputation. The present work reports a low cost optical sensing system for the above, suitable for the Third World. It uses a horizontally placed transparent Acrylic plate with a webcam placed below facing upwards. A white paper, backed by a black adhesive plastic sheet, covered the whole plate on the top. Light from a tubular fluorescent lamp entered the acrylic plate from a side and traversed the thickness through total internal reflection. At points of pressure applied from the top, the air between the paper and the acrylic plate got displaced and caused breakdown of total internal reflection. The scattered light rays from the white sheet were recorded by the webcam. Computer software on Java platform was developed to grab and analyse video data to display dynamic pressure distribution in artificial colour contours. Approximate pressure calibration was obtained using static and dynamic values obtained from subjects with normal and abnormal foot pressures. Time graphs of pressure at user chosen points were also provided. The developed system worked with satisfaction and is being used for clinical assessment regularly in a neighbouring country.

Abstract: A low cost dynamic foot pressure measurement system was developed earlier by our extended group which gives the approximate pressure variation at different points of the foot while walking, which is working satisfactorily in a clinical setting. However, from a scientific point of view, a more accurate and rigorous calibration is desired. The device uses a horizontally placed transparent acrylic plate covered by a white paper, and backed by a black adhesive plastic sheet on the top. Light from a tubular fluorescent lamp entered the acrylic plate from a side and traverses the thickness through total internal reflection. At points of pressure applied from the top, the air between the paper and the acrylic plate got displaced and caused breakdown of total internal reflection. The scattered light rays from the white sheet were recorded by the webcam, and the intensity of light is presumed to represent pressure applied at that point.

It has been suggested in earlier work using similar devices that static and dynamic pressure calibrations are different. In the present work a four wheel wooden cart was devised with weights placed on top, which could be pulled along the sensitive surface at different speed. By analysing the pressures created by the wheels for these different speeds, an understanding was achieved regarding the variation of pressure with the time of contact. It was also confirmed that the intensity of light in a pixel was related to the pressure value directly.

Finally the average pressure created by a walking person was analysed critically. Two humps at the beginning and at the end of the step were observed, which suggests that because of the nature of walking there will be such increases at these phases of the footstep. This agrees with foot pressure analysis done theoretically earlier by other groups. Therefore, when complete this work will increase the capability of the foot pressure measuring system developed at relatively low cost.

10. DEVELOPMENT OF A DUAL FREQUENCY SYSTEM OF FOCUSED

IMPEDANCE METHOD (FIM) FOR MEDICAL DIAGNOSIS

Md Abdul Kadir, K Siddique-e Rabbani

Dept of Biomedical Physics & Technology, University of Dhaka, Dhaka, Bangladesh


Abstract: Focused Impedance Method (FIM) developed recently by our group at Dhaka University provides an opportunity for localized impedance measurement down to reasonable depths using surface electrodes, and application of FIM may give more specific results in the detection and diagnosis of diseases and disorders like pneumonia, certain cancer, etc., if measurements are carried out at several, or at least at two different frequencies. FIM essentially measures the impedance around a region using tetrapolar technique in two orthogonal directions using special configurations of electrodes. This paper presents the design and fabrication of the instrumentation of a dual frequency version of FIM, operating at 10kHz and 100kHz. Two separate oscillators with separate current drive circuitry were used in the design to supply alternating currents with constant amplitude through circuitry based on op-amps. Potentials developed across two other electrodes were measured through a well designed bioelectric amplifier to

31

minimize associated noise. The signal was then converted to dc to get a numerical output through a digital multi-meter. The system has a manual switching for the frequencies, and for changing the connection to the electrodes in order to change the direction of impedance measurement in the prototype. Performance test on the finished device gave values as desired. This instrument would be used to get preliminary information on the measurement on human body, particularly addressed to the diagnosis of Cervical Cancer, and characterization of already detected breast tumours. In a subsequent design all the switching will be done automatically using a microcontroller or a personal computer.

Abstract: Cervical cancer occurs in the lining of the cervix and slowly, over time, forms a malignant tumor. Cancer of the cervix is the second most common cancer affecting women in the world and the commonest cause of cancer related mortality. It is highly curable when found and treated early, at the pre cancerous phase known as Cervical Intra-epithelial Neoplasia (CIN). Visual Inspection with acetic acid (VIA), Pap smear test and Colposcopy test are the existing methods of screening for the presence of premalignant changes in superficial cervical tissue. A group at Sheffield University, UK demonstrated that it is possible to distinguish between normal squamous epithelium and Cervical Intra-epithelial Neoplasia (CIN), an early stage of cervical cancer, by measuring electrical impedance at different frequencies using conventional tetrapolar impedance techniques. They showed that cell structure, shape etc. change in cancer and electrical impedance can detect this change instantaneously.

Focused Impedance Method (FIM) developed recently by our group at Dhaka University provides an opportunity for localized impedance measurement, and application of FIM may give more location specific results in the detection and diagnosis of cervical cancer. From the spectral nature of the impedance in case of cervical cancer, it also seems possible to obtain diagnostic information through measurements at only two suitable frequencies, instead of a range of frequencies, which we are targeting at present

In the present work firstly an appropriate electrode configuration is being developed using which measurements will be carried out in phantoms. Then real life measurements will be carried out to see its viability in comparison to traditional methods. The electrode configuration will be modified if needed, and a comparative study will be made between these different configurations. The results will allow us to decide on the technique which will then be used for clinical trial on human subjects with and without Cervical Cancer. Finally the results of the clinical trial will give us adequate information to use the best option as a diagnostic tool.

Abstract: This paper describes an electronic mobility aid for the visually handicapped using ultrasound echo pulses, and delivering the distance information through nerve stimulation. This combination of sensing and information delivery is a new idea of our extended group which developed an initial model earlier. The frequency of the nerve stimulation is varied according to the distance between the person and the obstacle, increasing with decreasing distance. This was designed to match a normal psychological reaction of getting alarmed when the frequency of a sensation increases, ultimately allowing the person to move away if the object gets too close. In a practical set up an ultrasonic transmitter and a receiver will be mounted on two sides of a sunglass, and the wearer can sense the position of objects around by turning the head. The changing frequency of stimulation will allow sensing the movement of an object as well. A frequency of 40kHz was chosen for the ultrasound sensors to get a sensitive range of about 10m.

The transmitter circuit was designed using an astable or free running pulse generator which drives the ultrasound transducer. Because of its high resonant characteristics, a damped sinusoidal waves result. The receiver transducer picks up the reflected pulses which are amplified and processed to produce square pulses. The time delay between the transmitted pulse and received pulse was used to produce a proportional voltage through a triggered ramp generator. This voltage was the input of a voltage controlled oscillator (VCO) which gave an output frequency depending on the modulating voltage. This output was used to drive a nerve stimulator which produced 200V pulses with a width of about 1ms.

In the earlier prototype the useful range was short, about a few feet. The present work was mainly taken up to extend the range. This was achieved by driving the transmitting transducer with high voltage of about 150V by designing necessary high voltage circuitry. An experimental prototype, developed on a bread board, gave a reasonably large output even at distances of 4 meters within the laboratory. From the size of the received pulses from the ultrasound transducer, it is expected that it may be used to a range of about 10m, which was the maximum range initially desired. When completed, this device will be helpful for the blind people throughout the world at an affordable cost.

13. PATIENT RESPONSES IN A PHASE 1 CLINICAL TRIAL OF TARGETED ALPHA THERAPY FOR METASTATIC MELANOMA

[email protected]

Targeted alpha therapy is based on the cytotoxic properties of the high linear energy transfer (~ 100 keV/µm) and low range (20-80 µm) of alpha particles. Monoclonal antibodies are labeled with an alpha emitting radioisotope to form the alpha-immunoconjugate. Our phase 1 melanoma trial with intravenous injections of up to 25 mCi of the 213Bi-cDTPA-9.2.27 demonstrated that alpha therapy could regress solid tumours without any adverse events1.

33

The effect of key parameters such as melanoma inhibitory activity protein, age, sex, injected dose, lactate dehydrogenase, disease stage and treatment dose were examined. Thirty nine patients with stage IV melanoma or in transit metastasis were treated with activities of 55-1035 MBq. No adverse events of any type or level were observed, so the maximum tolerance dose was not achieved.

An objective partial response rate of 10% was observed for partial response, with 40% stable disease for 8 weeks and a median survival of 8.9 months. Survival analysis showed MIA, disease stage, LDH and treatment effect to be significant prognostic indicators for survival. The lack of dose response is indicative of the importance of the tumour capillary permeability, without which alpha therapy cannot function2.

14. PALLIATIVE RADIOTHERAPY IN DEVELOPING COUNTRIES

Abstract: The International Agency for Research on Cancer predicts that cancer incidence in developing countries will increase dramatically in the first two decades of this millennium. Already some 80% of cancer patients in developing countries present with incurable disease. In many cases pain is a severe problem and palliation is needed to improve quality of life as well as extending survival.

This paper will consider the physical and clinical aspects of palliative radiotherapy (PRT), choice of radiation modality, alternative approaches to imaging and therapy and cost-benefit considerations.

The potential benefits of a dedicated palliative centre include lower cost and therefore more centres, enabling more patients access to regional palliative care.. Whilst there is an obvious need for palliative radiotherapy, simple curative treatments could also be managed.

Co60 radiotherapy has important advantages in developing countries, because of the higher initial cost of a linear accelerator, as well as the need for reliable power supply and the level of skill required by linac technicians and physicists. The beam characteristics of both Co60 units and low energy linacs are compared and both are found to be acceptable for palliation.

The concept of telemedicine is also discussed, using mobile phones and internet communication to allow rural clinics to receive support from specialists based in the cities, to send images for remote diagnosis and remote dose planning for radiotherapy.

Abstract: Cervix cancer among Bangladeshi females is very common. Radiation therapy is one of the

modality to treat it. The common modality of treatment of early stage cervical cancers Ιb, ΙΙa and ΙΙb cases is through a combination of intracavity applicator (radiation) and external beam irradiation (radiotherapy) delivering required dose to the cervix and significantly reduced dose to the surrounding

34

normal tissues and vital organs like rectum and urinary bladder. The main goal of the radiotherapy treatment is to maximize the radiation dose at lesions (tumor volume) and minimize dose below the tolerance level in the surrounding normal tissues. Cervix cancer treatment is a critical task as different important organs like rectum, bladder, parametrium, fornix have different radiation tolerance levels. Conventional rectangular block shields the rectum area and urinary bladder but the resultant dose fall off is very rapid beyond point ‘A’ (Point A is defined to be 2 cm superior to the external cervical OS and 2 cm lateral to the cervical canal) resulting in dose inhomogeneity to the target volume.. To overcome this problem, an alternative method is proposed to protect the unnecessary central axis radiation dose to the critical organs by using “Wedge shaped Mid-Line Block (WMLB)

The wedge shaped mid-line block has a rectangular shape at the center and wedge shaped slope on both

sides. The central rectangular portion with an area 10×4cm² and thickness of 5.5 HVLS (Half Value Layer Surface) ensure nearly 100% shielding up to point A. The wedge shaped portion of the block

covers an overall area of 10×10cm² on both sides of the uterine canal for a source to surface distance (SSD) of 80 cm (the edge of the block being named point B). Beyond this point and up to the edge of the beam, there is no shielding, since the contribution of intracavity dose is considered to be nil. To estimate the thickness of the block between point A and B a lateral 100% dose profile was generated for Fletcher- Suit applicator at the level of point A using computer. The fall off of dose between point A and B was estimated in percentage by normalising to the dose at the point A (taken as 100%).

This paper presents the attenuation characteristics of the fabricated WMLB. Cobalt 60 was used as radiation source and Electrometer PTW UNIDOS and Farmer ion chamber (0.6 cc) were used to carry out radiation dose measurements. Attenuation close to 97% was obtained using the WMLB from the central axis to point A to compensate the fall of dose, which represents a good achievement.

16. LESSONS FROM MAJOR RADIATION ACCIDENTS IN RADIOTHERAPY PRACTICES

Abstract: Radiation therapy uses high-powered x-rays, particles, or radioactive seeds to kill cancer cells. There are two forms of radiation therapy:

• External beam radiation, which is the most common form. This method carefully aims high powered x-rays or particles directly at the tumor from outside of the body.

• Internal beam radiation, which uses radioactive seeds that are placed directly into or near the tumor. Internal beam radiation is also called interstitial radiation or brachytherapy.

Radiation accident or injury attributable to radiotherapy is a topic that has attracted ample attention in the literature. However, the literature is clearly devoid of compilations regarding the effects of ionized radiation accidents. Lessons have been learned from investigations into a relatively large number of accidents that have occurred in radiotherapy practices. In order to prevent accidents in radiotherapy, it is important to learn from accidents that have occurred previously. Lessons learnt from a number of accidents are summarized and underlying patterns are looked for in this paper. Accidents can be prevented by applying several safety layers of preventive actions. Categories of these preventive actions are discussed together with specific actions belonging to each category of safety layer. This paper provides an overview of the lessons learnt and specifically considers the human actions and omissions that have resulted in accidents.

Abstract: Cancer is one of the deadly diseases which affect a large number of populations worldwide. There are many types of cancers depending on their origin and where it grows. Now-a-days it is treated using many different techniques, for example surgery, radiation therapy, hyperthermia etc. Hyperthermia is a process where heat energy is used to destroy/weaken the cancerous cell. We proposed Infrared or Far Infrared light radiation can be used for hyperthermia process instead of currently used methods. The proposed infrared radiation cancer treatment system consists of two functional sub system or units. The intensity control sub unit has controllable knobs by which heat radiation incident on tumor volume can be adjusted as per calculation done by the Medical Physicist to raise the temperature to the desired value. The shape control sub unit produces a shape of focused radiation that matches the shape of the tumor target volume, so that surrounding normal tissues gets minimum (safe) level of heat radiation. The power control circuit changes the intensity of radiation by changing the conduction angle of the power device, triac. The conduction angle is changed by step selection Resistor, and fine tuning of power controlled by a continuous variable resistor within that selected range. The desired shape is constructed by controlled sub unit using multi leafs heat radiation absorber or obstructers. We borrowed the idea of multi leaf collimator used in Multi million taka recently introduced ionizing radiation therapy LINAC system for cancer treatment. By placing the each multi-leaf component at desired position any shape can be simulated. In this project for simplicity we used eight leafs for shape control. Higher number of leafs definitely would increase the precession of the shape to be constructed. The inward or outward position of any leaf is controlled by a small size digital stepper motor connected to it, whose steps are controlled by sequences of digital pulses. The proposed multi-leaf intensity and shape controlled infrared system for cancer treatment has been designed and found to be working.

Abstract: In Bangladesh number of X-ray machines is increasing at a rate accelerated by the recent economic expansions. Despite the low dose per examination, the magnitude of practice makes the diagnostic X-ray the dominant source of medical radiation exposures. It estimates that the average individual and collective doses to the world population from diagnostic medical X-ray examination range from 0.3 to 2.2 mSv and 1.8 to 5 mSv respectively. The X-ray installations, therefore, deserve attention from population dose perspective. This study was undertaken to survey the radiation protection management in several X-ray installations of Narayanganj district. To get a real picture of radiation protection management of a specific area this work is necessary. It will give us an assessment about the radiation protection condition of X-ray installations of our country. A questionnaire was used to collect the raw data about a specific X-ray installation. Questions were divided in some basic categories such as

36

general information i.e. particulars of X-ray technicians, availability of protective equipments etc. and technical information i.e. types of X-ray unit, maximum kV and mA etc. Some technical observation such as availability of warning signal, area of X-ray room etc. were also noted. Measurement of radiation exposure in each X-ray installation was carried out at different locations of that specific installation by using a survey meter during typical X-ray examination.

Present study gives the information that only 12% radiation workers are trained and only 10% installations having a proper control panel are considering radiation protection for X-ray operator. About 33% of the total installations have standard size X-ray room i.e. room with area above 16 meters. The lead apron, which is an important radiation protection item for the operator, is available in 83% installations. Only 28% installations have the entrance door with lead which is also essential for the protection of visitors standing out side of the X-ray room. In the present study, skin entrance dose has been calculated by using two different empirical formulae. The variation of result has also been calculated. Then the organ dose calculation for different organs was done based on the skin entrance dose and International Commission for Radiation Protection tissue weighting factor. The minimum value of

organ doses were measured and for Gonads it is 4.33 µGy, for bone marrow, 4.33 µGy, for bone surface,

0.36 µGy, whereas, the maximum value of organ doses measured are for Gonads, 75.76 µGy, for bone

surface, 4.87 µGy and for liver, 24.33 µGy. Study of this work thus compares well with the works which had already been done abroad. The lay out of the X-ray room has also been drawn and the dose rate at various locations was measured by using a dose meter. These layouts should help to develop a standard lay out plan for X-ray room.

The results of this study will help us to understand the radiation protection management system of most of the X-ray installations of our country and take necessary actions to implement the rules or regulations suggested for the radiation protection of the diagnostic X-ray installations. In coming years, there will be more clinics and government hospital and it is therefore, suggested that in future, a more comprehensive study be carried out for dose absorbed by patients undergoing radiological investigations, the occupational workers, the public at large (for example, relatives accompanying the patients). It will then give a more general picture of the radiation protection management in X-ray installations. However, the results presented in this work should partly serve as base line to establish a full-fledged radiation protection procedure for our country.

Abstract: Biological internal dosimetry performed on fifteen normal patients who underwent a routine diagnostic investigation with I-131. Tracer kinetics and bio-distribution for I-131 were evaluated by a dual head ECAM gamma camera, with planar images, and a thyroid uptake system. A water phantom of known activity and volume were used to find the cross calibration factor and to convert bio-distribution data into activities. These data were used to plot a time-activity curve and used to determine effective half-life of I-131 in different source organs for the patient. Thus the cumulated activities of I-131 in thyroid and in different organs, as well as the residence times at different organs are calculated. These values with a recent version of software program MIRDOSE3 was used to calculate the absorbed dose per unit of activity in the target organ. The absorbed doses to thyroid as a target organ in normal and healthy

37

Bangladeshis were calculated and found in the range of 592-1150 rad/mCi of I-131. The effective dose equivalent at the time of highest thyroid uptake (23%) was 3.56E+01 rem/mCi. Thus gamma camera based, patient specific internal dosimetry is feasible using I-131. Sequential planar image can be used to obtain cumulated activity in different source organs.

Abstract: Modern radiotherapy relies on accurate dose delivery to the prescribed target volume. Before clinical use, the output of photon and electron beams produced by external beam radiotherapy machines must be calibrated. A study on comparison of three types of ionization chamber used in reference dosimeter as absolute dosimeters is presented here from recent commercial use .Also a discussion of using more practical solid materials as phantom materials such as polystyrene; Lucite, A-150 tissue equivalent plastic, Solid Water (WT1), Solid Water (RMI-457), Plastic Water or Virtual Water beside the standard material Water is also mentioned.

Abstract: A study of area monitoring in a nuclear medicine department’s new physical facility was performed for 3 months to ascertain the level of radiation protection of the staff working in nuclear medicine and that of the patients and patient’s attendants. Exposure to nuclear medicine personnel is considered as occupational exposure, while exposure to patients is considered medical exposure and exposure to patients’ attendants is considered public exposure. The areas that were considered the sources of radiation hazard were (a) the hot laboratory, where unsealed isotopes, radionuclides, generators are stored and dosages are prepared, (b) the patients’ waiting room where the radioactive nuclides are administered orally and intravenously for diagnosis and treatment and (c) the SPECT rooms, where the patients’ acquisition are taken. The monitoring process was performed using the TLD supplied and measured by the Health Physics Division of Bangladesh Atomic Energy Commission. The result shows no over-exposure of radiation from any of the working areas. The environment of the department is safe for work and free from unnecessary radiation exposure risk.

Centre for Experimental Radiation Oncology, St George Cancer Centre Gray St, Kogarah NSW 2217 Australia

[email protected]

Abstract: Vanuatu lies off the East coast of Australia with a Melanesian population of ~300,000. Of the working age population, only one quarter are engaged in monetary activity and two thirds work as subsistence farmers. Major businesses are mostly owned by overseas interests and villages are rarely involved in commercial livestock and fruit & vegetable production. As such, Vanuatu is seriously disadvantaged financially when it comes to rural public health services. In 2008 there were 34 Health Centers and 6 hospitals in 6 provinces, supported by ~ 46 midwives and 40 nurse practitioners. A detailed review was undertaken of medical services in the villages and towns, with particular regard to equipment and training needs. Visits were made to the National Referral Hospital: Vila Central Hospital, Efate (Level 6); Regional Referral Hospital: Northern Districts Hospital, Luganville, Santo (Level 5); Level 3 Health Centres at Paunagisu Health Centre, North Efate, Fanafo Health Centre, Santo and Port Olry Health Centre, Santo and a Level 2b Dispensary: Erakor Dispensary, Efate. The following comments are pertinent to this report.

• Staff morale would be enhanced by availability of improved communications.

• Vacuum birthing equipment and ultrasound is requested.

• In-house training and distant education for improved morale, skill base and service.

• The villagers should provide voluntary maintenance support, so that accumulated funds can be spent on more important requirements.

• Increase in the retirement age so as to retain experienced staff.

• Microscopes needed for malaria and HIV in hospitals.

• Need for pressurized autoclaves, drip stands for IV infusion, baby scales and blood pressure measurement.

Overall recommendations

• Introduction of local, in-house apprenticeships at all levels.

• Increase in the retirement age so as to retain experienced staff.

• Engineer required for equipment repair (Engineers Australia support).

• Support for cervical cancer screening.

• Palliative pain centre is required for end-stage cancer patients.

• Telemedicine via mobile phone technology using the existing transmission towers.

This review was funded by a grant from the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM).

Abstract:

Introduction: We introduced the portable EEG in February 2010 for the first time in Bangladesh to extend the service for difficult to reach population. Our target is to provide high technology based service for the people with neurological and neuro-developmental disorders.

Objective: This study was performed to describe the electro-clinical profile and evaluate the value of portable service in the context of our socio-economic and disease pattern in children.

Methods: We have reviewed the clinical criteria, referral pattern and the EEG findings of the children which were performed with the portable EEG machine during the period of February to December 2010.

Result: Total 69 EEGs were performed by the portable EEG machine. Tests were performed for the children who were difficult to move from the hospital care, i.e., patient in coma, in status epilepticus at Dhaka Shishu Hospital, Mirpur Shishu Hospital, ICU of Comfort Diagnostic Center, ICU of United Hospital, ICU Care Hospital, Home in Dhaka city. In addition, we organized clinics for children with neurological disorders including suspected epilepsy in two villages of Hobiganj in February 2010 and in Kishorganj in December for the first time in the country. The diagnosis of Epilepsy was confirmed in some of the children with immediate EEG and appropriate treatment could be started for their epileptic seizures on the spot.

Conclusion: Medical technology is the essential part of health management and should be available at all levels. It is possible to arrange appropriate diagnosis and treatment for Epilepsy and related neurological disabilities among the population at remote areas.

25. USE OF AN INNOVATIVE INDIGENOUS ELECTRICAL GASTROMETER IN ASSESSING GASTRIC ACIDITY

Abstract: As a trainee rural doctor the author noticed that many patients complain of acidity problems, i.e., problems related to digestion. However, no equipment capable of measuring such conditions of acidity quantitatively are available in the hospitals of Bangladesh, and treatment is carried out based on the idea of the doctor only. This sometimes leads to complications, and even death may result in certain cases. Equipment to measure pH in the Esophagus are available in advanced countries, but these are expensive, and have not found much in use in Bangladesh. This experience led the author to develop an innovative electrical gastrometer that takes measurements from the saliva of the patient. Measurements were taken on more than 1000 human subjects including normal subjects and patients with different degrees of acidity problem. The results indicate the efficacy of this instrument. Treatment given to these patients based on this estimation also produced relief in majority of cases.

Abstract: ECG equipment is vital for diagnosis of cardiac problems. However, such equipment come from the economically advanced countries at a huge cost in both procurement and maintenance, and therefore cannot offer services to a large population in the Third World. The only solution is to design and develop such equipment in individual countries by developing local expertise. With about three decades of experience, the Dhaka University group has taken a step towards developing prototypes of low cost ECG equipment for dissemination to the healthcare service providers. Since personal computers are available widely, a PC based solution was the target. This paper presents the detailed design and development of a PC based ECG equipment where optimized choice of components and of the design have been made keeping the cost and maintenance in view, but not sacrificing the quality, and incorporating necessary safety features to protect the patient from known hazards. Outputs obtained from human subjects are of reasonable good quality, and have been verified using standard ECG equipment. The PC based ECG system will allow digital post processing of signals for improved diagnosis through software. The same PC could be used for acquiring data from various other sensors and equipment to provide comprehensive health monitoring in the rural areas. In future, this could be the basis of a nationwide telemedicine network.

Abstract: A portable battery powered miniature ECG monitor with a small graphic display screen has been developed at low cost which can be used in rural areas, and may be carried by medical practitioners in their bags for on site service to patients. This involved development of electronic hardware based on a microcontroller unit (MCU) and necessary software. The electronic hardware consisted of an analogue part and a digital part. The analogue front end amplified the feeble ECG signal eliminating much larger mains borne 50Hz noise, and was based on an Instrumentation amplifier and a few operational amplifier IC’s. Since the whole system is battery powered no electrical isolation was necessary from the considerations of safety and noise reduction. The digital section is based on a microcontroller unit (MCU), Atmega 32, with built-in analogue to digital converter. For graphics display a 128 x 64 pixel monochrome LCD unit (Topway LM6063) with integrated controller (Ks0713) was used. This displays graphics through 8 vertically displaced rows, each of 128 x 8 pixels, and plotting 8 vertical pixels at a time sequentially from left to right for each row. Firmware (base software) necessary to control the graphics was developed and stored in the MCU. Software was developed to acquire analogue data sequentially in equal intervals of time, converting these to digital values, simultaneous calculation of co-ordinates of display pixel to be plotted, performing algorithm to join the current point

41

with the last plotted point through a line, and sending all this information to the graphic controller. The software also displayed the total time of a horizontal plot numerically on a corner of the screen by acquiring timer pulses from the MCU and performing necessary calculation. Both firmware and software were developed in ‘C’ language. Using facilities available in the MCU, 5 external control buttons provided functions to shift the display up and down, to change the horizontal scale of display, and to freeze the display at any time. ECG from real human subjects was obtained and displayed using this device, and was found satisfactory. The developed hardware was mounted in a compact box with integrated battery. Field trial and further improvement will be needed before it can be given out to users. A little modification will make it suitable for ambulatory monitoring, with data stored in an SDRAM, which can later be read into a PC and analysed by a doctor.

Abstract: SpO2 stands for either ‘Saturation of Peripheral Oxygen’ or ‘Oxygen saturation on Pulse Oximetry’. It is directly related to the arterial blood oxygen saturation level and is usually called the fifth vital sign, which carries great importance in medical diagnosis. A pulse oximeter is a non-invasive device to measure SpO2 and heart beat rate. Commercial devices are available from foreign manufacturers, but these are very expensive, and their widespread use in our rural health centres is not practicable. A locally developed device can reduce the cost and fulfill this important gap.

In a pulse oximeter light of two different wavelengths is passed through some limbs of the body, usually the finger tips or ear lobes, and is modulated by the pulsatile blood flow therein. The amplitude of the alternating current component generated by the processed light incident on the photo detector is used to calculate the molecular extinction co-efficient that relates to the degree of oxygen saturation. To eliminate contributions of skin colour and other body tissues, lights of two different wavelengths are used. Two LEDs, a red one having a wavelength of 660nm and an infrared LED having a wavelengths of 900nm, provide two different absorption values which depend on the presence of oxyhemoglobin and deoxyhemoglobin in the blood. Based on Beer-Lambert law, the logarithmic ratio of these absorption values can be analysed to obtain the desired value of SpO2. The necessary calculation is performed using a microcontroller. Side by side the pulsatile signal can be analysed through software in the microcontroller to get the heart beat rate. When ready this device can be produced at low cost so that it can be distributed to rural health centres at an affordable cost.

Abstract: Many statistical investigations assert that cardiovascular disease is the prominent cause of death for several million people annually. Novelty in public habits and lifestyles has introduced newer maladies that the health care system of a country has not always been able to vie with. Need for efficacious preventive cardiology has been advocated by many researchers. An imperative component of effective preventive cardiology is to collect, monitor and maintain health data of the target population over an extended period of time. In this paper, we propound a proposition of a cheaper methodology for collection, distribution and dissemination of information pertaining to the cardio vascular system for rural population in Bangladesh. Major incidents of cardiovascular diseases (CVD) in rural population of Bangladesh include different abnormalities that are manifested in ECG, ankle-brachial index, arterial compliance and insufficient hemoglobin in children and pregnant women. A non-invasive approach can be advocated for preliminary assessment of CVD by collecting the biomedical signals such as 3-lead ECG, Phonocardiogram, Plethysmograph pulse oximetry and blood pressure. As all the signals can be obtained in a non-invasive way, this approach offers several benefits such as the low cost of diagnostic tests, low average time of data collection per subject, low capital investment, automated record keeping and possibility of simultaneous acquisition of multiple signals. We designed a low cost data acquisition platform by using locally available devices consists of several units- a signal acquisition unit including transducers , signal conditioner and amplifier unit, a digitizer, USB interface and a computer .After collection of data it can be stored and sent via internet to central server for analysis. This scheme can be implemented with fewer difficulties and can perform a vital rule in public cardiological health care system of Bangladesh.

Abstract: Osteoporosis (bone degeneration) is a disabling condition, particularly at old age, and for women, and needs to be diagnosed early for medical intervention. Specialised X-ray based bone densitometry equipment are available, but are expensive and not widely available in Third World countries. It was thought that an improvisation is possible using conventional X-ray equipment which is available in most Third World hospitals. The idea was to have an X-ray of a specific bone of a subject on a conventional X-ray film together with a stack of aluminium strips providing different thicknesses and

43

placed in the neighbourhood. Next the optical densities of the developed X-ray film would be measured at desired bone locations and at the positions of the aluminium strips. The latter would provide a means of calibration and standardization for the bone density, and will eliminate variations due to film quality, exposure, and film development processes. In this work the necessary optical instrumentation was developed using a number of red LED’s as an extended source the light beams from which was diffused to obtain uniform lighting over a circular area of diameter 1cm, where the X-ray film is to be placed for measurement. The transmitted light was concentrated onto a photo transistor and necessary electronic circuitry was developed to obtain digital readout of light intensity values. Measurements were carried out on two healthy young subjects and two aged patients. A significant difference was obtained as expected. This now needs to be calibrated with a standard bone density measuring equipment to make the device practically useful.

31. DEVELOPING A REAL-TIME PATIENT CARE PROTOTYPE

Abstract: In our country Bangladesh, patient monitoring is still carried out by manual process. Here in the country, emergency medical services to the victims of disasters are conducted by manually measuring patient conditions. Patient assessments and documentation are also performed manually. Though in recent years some telecom service providers start providing health service communicating over cell phones but these measures are inadequate in disasters which occur frequently in our country. To achieve the goal of vision 2021 to make a glorious Bangladesh, there is a need to develop a new patient care prototype to the disaster response arena through the digitization and automation of the emergency medical services in disasters by which each step of the rescue operation in a trauma will be e-compatible. IEEE 802.11 (WiFi) wireless based technology can play a significant role to provide necessary network infrastructure to build up this real-time patient care prototype at the disaster sites, as it is economically viable in coastal areas and hilly regions, which parts of our country are the most vulnerable to disasters, rather than deploying new optical fiber in these areas. This paper mainly concentrates on the development of a real-time patient care prototype to coordinate and enhance care of casualties in a natural or a human-made disaster by the use of IEEE 802.11 (WiFi) wireless based technology.

32. NEED TO DECENTRALIZE AND DEVELOP ASSISTIVE DEVICES IN THE RURAL AREAS OF BANGLADESH.

Many types of Assistive Devices (including Orthosis, Prosthesis, Brace Splints) have been developed for the disabled, but are not available in rural areas of Bangladesh. In Bangladesh some are available in Dhaka, but not in the other places, and obviously not in rural areas. It is

44

necessary to develop facilities for offering such services, including facilities of fabrication of make such devices, in rural areas at a minimum cost. A policy for decentralization of such facilities is needed for this purpose. The cost may be minimized and sustained services may be achieved through procurement of locally made low cost machines and tools (oven for melting poly propylene, welder, heat-gun, etc.) and development of skills among the assistive device makers. A close collaboration among socially conscious researchers in Bio-Medical science and Technology, and a facilitating policy of the Government is required to take necessary steps in this regard.

Abstract: In modern life, we are surrounded by Electromagnetic (EM) radiations originated from various appliances used in daily life. Interference of the EM waves has bad impacts on human beings like neurological effects, physiological stress on human body and even genetic mutation that results in cancer. All the devices used in daily life emit radiations having their own maximum level of emissions and the distance at which they have minimal effect. In this paper, medical aspects have been studied for the effect of the EM waves along with the latest inventions on shielding these waves. Based on the surveys, a living room has been designed with minimum effect of harmful radiations even if it is fully equipped with the electronic items. A future idea has also been given for saving power by converting the stray microwaves in the atmosphere into current with the help of a receiver.

Abstract: It is only about 100 years since electricity generation started, 70 years since radio transmission and 30 years mobile telephone system came into existence. As the world is being industrialized and technological revolution continues, there has been an unprecedented increase in the number and diversity of electromagnetic (EMF) sources. While all these devices have made our lives richer, safer and easier, they have been accompanied by concerned possible health risks due to their electromagnetic field (EMF) emission.

45

For sometime a number of individual have reported a variety of health problems that they relate to exposure to EMF. While some individuals report mild symptoms and react by avoiding the field as mush as they can, others are so severely affected that they cease work and change their entire lifestyle. So, repeated sensitivity to EMF has been generally termed “electromagnetic hypersensitivity” or “EHS”.

There is a wide range of estimates of the prevalence of EHS in the general population. A survey of occupational centers estimated the prevalence of EHS to be a few individual per million in populations. However, a survey of self-help groups yielded much higher estimates. Approximately 10% reported cases of EHS were considered severe.

There is also considerable geographical variability in prevalence of EHS and in the reported symptoms. The reported incidence of EHS has been higher in Sweden, Germany and Denmark than in the UK, Austria and France. VDU related symptoms were more prevalent in Scandinavian countries and they were commonly related to skin disorders than elsewhere in Europe. Symptoms similar to those reportedly by EHS individuals are common in the general population.

EHS is characterized by a variety of non-specific symptoms that differ from individual to individual. The symptoms are certainly real and can vary on their severity. Whatever it causes, EHS can be a disabling problem for the affected individuals.

A case study has been carried out very recently among the employees of a NGO organization in an office block with an 11kV power line passing near one of the walls. Measurements were carried out on the magnetic fields produced. It was found that people working near the high voltage side of the building developed various complains including headaches only within a few weeks, it may be considered as hypersensitivity of the people towards the effect of EMF. After relocating these persons to areas distant from the high voltage lines, the physical symptoms disappeared.

Abstract: This paper presents the results of migration behavior of 137Cs in various type of soil (agriculture

soil, land soil, high land soil and river soil) profiles by γ-spectrometer which were sampled (0-50 cm depth) in the Sylhet sadar upazila areas of Bangladesh. Migration of radionuclide is one of the most important factors to be considered when carrying out safety analyses of radioactive waste and opening a good absorber for the reduction of radionuclide from radioactive liquid waste generated from nuclear facilities. Laboratory based column experiments have been carried out with a fixed column length (50 cm) and diameter (5.34 cm) to determine migration depth, migration percentage and migration rate of 137Cs after passing 50 ml 137Cs aqueous solution and 4000 ml distilled water. The physio-chemical characteristics, soil-water characteristics and radioactive concentration of natural radionuclide of the soil were also measured. It was observed that the maximum migration of 137Cs was found at a maximum

46

length 0-10 cm in clay type of low land soil, 0-20 cm in clay loam textured of agriculture soil and 0-15 cm in sandy loam textured of high land and river soil. The downward migration depth concentration of 137Cs via de-sorption, diffusion or flow in clay type soil column layer is very small than that of other soils. These results indicated that locally available clay can be used as an adsorbent for the decontamination of liquid radioactive waste generated at nuclear facilities without any pretreatment.

36. DRINKING WATER DISINFECTION USING LOW VOLTAGE ELECTRICAL FIELD, AN INNOVATIVE METHOD TARGETING THE

RURAL POPULATION

Abstract: Surface water in rivers, canals, ponds, wells, etc. in the rural areas does not contain arsenic. Therefore removing or destroying diarrhoeal pathogens can render such water drinkable. However, to be of use in the rural areas, simple low cost techniques are needed. One of the authors (KSR) first thought of using low voltage electrical fields to remove such pathogens in water using the method of electrical drift, and carried out some preliminary tests many years back showing indications of success. The idea stemmed from information that most bacteria carry a negative surface charge. It was thought that by simply applying a low voltage across a enclosed water volume, it may be possible to push such negative charge carrying bacteria towards the positive electrode (anode). The water around the negative electrode (cathode) should have reduced concentration of pathogens rendering the water drinkable. The present work was taken up to test this idea through microbiological investigation. Techniques were developed to apply a voltage across a water volume taken in two horizontally placed PET bottles linked through a short piece of tight fitting soft plastic tubing. Pond water was treated in this manner for about 30 minutes using 3V dc and water samples were collected from the two ends. Microbiological investigation for total coliform (TC) done at NGO forum for drinking water showed approximately 4 times reduction of bacterial concentration at the cathode region, and several times increase at the anode region, in agreement with the initially conceived idea. On the application of 30V, the concentration reduced further at the cathode, but the concentration at the anode was less than that obtained for 3V. It was hypothesized that nascent oxygen generated at the anode contributed to a destruction of bacteria at the anode. It was not assessed whether water with the reduced concentration at the cathode would be safe to drink or not. However, taking a parallel run on a method called SODIS, promoted in the Third World by a Swiss organisation, where water in a transparent PET bottle is left in sunshine for 5 hours, we found it to have less reduction of TC compared to that at the cathode after treatment in our method. Further work is being carried out at a facility offering a better microbiological discrimination.

37. DRINKING WATER DISINFECTION AT LOW COST FOR RURAL AREAS USING SOLAR THERMAL PROCESS

Dept of Biomedical Physics & technology, University of Dhaka, Dhaka, Bangladesh

Abstract: Surface water in rivers, canals, ponds, wells, etc. is free of arsenic and is available in most Third World villages. By destroying diarrhoeal pathogens such water may be rendered drinkable. Past scientific

work has shown that all diarrhoeal pathogens may be destroyed by heating water to 60°C and maintaining it for about half an hour, which is also the technique of milk Pasteurisation. The author has innovated very low cost methods and techniques to destroy such pathogens by raising the water temperature to more than

60°C in about one and a half hours using solar energy. Microbiological tests on treated pond water have borne it out. The device is basically a flat plate solar water heater, but the innovation lies in the use of very low cost and easily available materials like hay, bamboo trays and transparent polythene or polypropylene sheets or bags. A unit for 5 litres will cost about Taka 150 (about US $2.00), which can treat about 10 litres in two harvests on a typical sunny day, and will last months if used carefully. Pre-filtration using a normal cloth will improve the quality of the water. An NGO successfully introduced this device among the river gypsies in a part of Bangladesh. For rainy days, a simple open funnel has been contrived using the same polythene sheets which can help collect a large amount of rainwater which is good for drinking. Extra amounts may be collected for future storage. Microbiological tests by other

groups have shown that diarrhoeal germs are destroyed even at 55°C in this device innovated by us. The extra role of UV in sunlight has been invoked to explain this result. For coastal areas with salinity, attempts are being made to make low cost solar distillation units to give reasonable outputs of drinkable water.

Flood water may be made drinkable by making all the above devices on a common raft. Each family can make such units on its own and will not depend upon common initiatives and infrastructures which are sometimes difficult to organize in the villages. The devices may also find use globally in post disaster periods, after cyclones, earthquakes, civil wars, etc.
