BACKGROUND
R
adiology has traditionally been considered
inseparable from ‘films’, classically in the
form of X-ray plates but gradually also
including films incorporating images from
US, CT and MRI.
BACKGROUND
T
alk of ‘film-less radiology’ may therefore appear
anachronistic.
B
ut the future beckons a world in which the practice of
radiology may completely do away with the traditional
use of films
BACKGROUND
T
he seeds of film-less radiology were laid with the advent of
modalities such as MRI and CT, which were inherently
computer-intensive for both acquiring and presenting
clinically relevant images.
S
ince images from these newer modalities were basically in
a digital format, they could be treated in the same
manner as any other digital data.
INTRODUCTION
H
owever, the traditional habit of viewing all
images on films, require that these images be
also printed on films whether for reporting by
the Radiologist, for review by the clinician or for
long term archival.
BACKGROUND
W
ith the ever-increasing inclusion of
computer usage in the medical field and
specifically in radiology, this traditional
concept was beginning to be questioned.
BACKGROUNDT
he advent of computerized radiography (CR) and
digital radiography (DR) which can directly acquire
radiographs in the digital format, gave the final
push for the introduction of filmless radiology as
a viable proposition.
T
hus was born the concept of PACS
PACS
P
ACS is a computerized means of replacing the roles
of conventional radiological film: images are
acquired, stored, transmitted, and displayed digitally.
When such a system is installed throughout the
hospital, a filmless clinical environment results.
I
t is an integrated system of digital products
and technology that makes the
acquisition,storage,retrieval and display of
radiological images possible.
T
he PACS archive is expected to replace
radiology film libraries
WHAT IS PACS?
Components of the pacs system
The acronym PACS stands for picture
archiving and communication
system.
WHAT IS PACS?
So the 4 major components are:
1. Pictures:radiology,cardio,other modalities.
2. Archiving :deparment,specialty,enterprise.
3. Communication:LAN,WAN,VLAN’s.
4.Systems:Hardware,software,people,environm

TELERADIOLOGY
T
eleradiology is the transmission of images
and associated data between locations for
the purpose of primary interpretation or
consultation and/or clinical review.
I
t allows for remote access to images by
radiologists and clinicians.
G
enerally speaking, teleradiology can be
considered as a subset of telemedicine.
TELERADIOLOGY
ADVANTAGES OF PACS: Radiologist/physician perspective
The main advantage a PACS offers is the improvement in
efficiency resulting from electronic data handling
Source of new images and priors
Image manipulation and processing tools.
Tool for cooperation, consultation and demonstration
Allow for flexibility in location.
Faster turn-around times.
ADVANTAGES OF PACS
patient perspective
Fast availability of results
Share images between patients and physicians.
Exchange media(CD’s) allow for information
exchange between providers.
Access to any specialist anywhere in the world.
PACS AT CDICT
he PACS at CDIC was developed in order to address the need for
a robust, reliable, intuitive, efficient, and seamless platform for
transmitting, unifying and integrating diagnostic imaging data.
I
t is a web based PACs and teleradiology system thus it can be
accessed from any location where there is availability of a
computer and Internet.
I
t has been operating since August 2013.
PACS AT CDIC
Goals:
Provide expert interpretation of images, not
only in major urban, but in rural and medically
underserved areas as well where radiologist are
not available.
Promoting efficiency and quality improvement.
CHALLANGESH
igh dependence on availability of networks,IT infrastructure,hardwares.
S
oftware can have bugs
I
mage quality needs same amount of checking as in film world.
V
ast retraining effort.
U
sers need to become computer savvy
P
acs require a dedicated support staff.
CONCLUSIONP
ACS is an image and information management system.
I
t has a major impact on workflow and the way business is
conducted.
I
t requires a dedicated, well trained support staff.
C
onstant monitoring, QA and QC are critical components.
CONCLUSION
T
echnology is providing us with newer ways of
performing conventional jobs in a more
efficient manner and it is for us to decide
whether we would like to be a part of this
change that is sweeping the world of Medicine
gradually.
CONCLUSION
PACS is the future.
