Radiological Technology
• Radiological technology is a branch of Healthcare
• It is the science (& art) that deals with diagnosis of diseases (by imaging) and treatment of some diseases using ionizing radiation
Diagnostic Imaging modalities (branches)1. Using ionizing radiation• Radiography – Producing images
using X-rays• Plain radiography –
• Static images (chest, skull, abdomen..)
• Contrast Radiography • Static images (e.g. IVU….)• Dynamic images (Fluoroscopy) – (e.g.
Barium studies, Coronary Angiography)
Diagnostic Imaging ….
• Mammography• Tomography (conventional)• Computerized Tomography (CT)• Computed Radiography (CR)• Digital Radiography (DR)• Digital Fluoroscopy • Digital Subraction Angiography• Nuclear Imaging (Radio-Isotope imaging)
• Bone scan, renal studies, thyroid scans..SPECT, PET
Diagnostic Imaging ….
2. Other modalities (that does not involve ionizing radiation)
• Magnetic Resonance Imaging (MRI)• Ultra Sound scanning (US)
Therapeutic Radiography
• Treatment of Cancers using Ionizing radiation• Brachytherapy• Teletherapy
Brachytherapy• The radiation source is kept as close as
possible to the site of the tumour (usualy within the body)• To minimize the effect on the normal
structures• To maximize the effectiveness of the
treatment
• Using beta rays, gamma rays• Positron therapy
Teletherapy
• The radiation source is out side the body and at a distance from the tumour• Cobolt 60 sources• High energy x-rays• Linear accelerators
Who are we?
• Radiological technologists/Radiographers
• Are members of a team of health-care professionals who work in consort to maximize patient wellness
• Are Governed by a code of ethics and principles of professional conduct
Our Duties

Advancement in the field• PET-CT – hybrid images of PET & CT to
locate the tumours for treatment• SPECT-CT
Specific Risks involved
• Mechanical injury• Electrical injury• Radiation injury
Radiation hazards• Somatic effects
• Cancer• Cataract• Leucaemia• ………
• Genetic effects• Fetal Deformities• Infertility• Abortion• Still births
Radiation protection• Patient• Public – dose limits• Staff -• Self –
• Occupatienal dose limit (IAEA)• Monitoring
• Devices• Procedure
Competencies Required
• Patient care• Anatomy & Physiology (Structure and
function of the body)• Pathology (Identifying diseases)• Equipment (Physics, operation &
maintenance• Imaging techniques• Radio-Therapy techniques• Radiation protection• Quality control
Patient care
• Both fields (diagnostic & Therapy) deal with different catogories of patients
• Should demonstrate knowledge & skills in• Patient psychology• Effective communication• Patient care techniques
Training• Two years (Full time)• School Started in 1957• Still the same duration• No post basic training / continuing
education avenues• No avenues for upgrading
professional level
Achievements
• Starting BSc. Radiogaphy course at University of Peradeniya in 2006
Challenges
• To overcome the Objections for the Degree programme by some elements of the health sector..
• To stop emplyment of unqualified personnel as radiographers in private sector
Deficiencies in present training & suggestions
• Facilities incompatible with the number of trainees.
• Inadiquate duration• No procedure for Recruitment of tutors• CT, MRI, NM are not included • Extention of training period – 3 years• Implementation of a Proper recruitment
procedure
Future plans to upgrade the radiological technology in Sri lanka• Implementation of in-service
training programme • Convert the school to university
college?• External degree/lateral entry to
Bsc cources ?• Service minute - implement /
ammendment?
