Abstract
Definition
Teleradiology is a field of telemedicine. It electronically transfers a
patient' s radiological images from one location to another for the purposes of
interpretation and/or consultation from radiologists sitting at a distant
location. The main functionalities of a teleradiology system are image
acquiring, image compressing, image transmitting, and image displaying. The
basic requirements for a teleradiology system are:
- An Image Transmitting Station - It uses an image compression software
and networking interface devices (generally a modem) to transmit images
- A Transmission Network - It consists of networks such as the Internet,
phone lines, Wide Area Network, and Local Area Network
- An Image Receiving/Viewing Station - It consists of a computer with
monitor or printer
Teleradiology makes use of advanced software such as high-quality graphics
processing, image compression, voice recognition, etc. Most teleradiology
systems use Picture Archiving and Communication System (PACS) at the
transmitting as well as the receiving stations. PACSs are a set of computers
and networks, which are specifically meant for archiving, distributing,
receiving, and presenting medical images. Generally, standard Digital Imaging
and Communications in Medicine (DICOM) is used for archiving, printing and
transferring of the medical images. Teleradiology is increasingly used by
hospitals and institutions to gain accessibility of specialists and
sub-specialists (in remote location) for radiology services. A teleradiologist
can view a radiology report and provide a diagnosis without being present in
the same room as the patient. An additional advantage of teleradiology is the
availability of round-the-clock service. However, legislations by some
countries require teleradiologists to be within the country' s borders when
providing the services. The scope of this report includes the global market
for the following categories:
- Teleradiology Equipment - Equipment and hardware accessories required
for setting up a teleradiology system
- Teleradiology Software - Software solutions required for providing
quality teleradiology services
- Teleradiology Services - Revenue generated by providing teleradiology
services
