Teleradiology - Why?Teleradiology - Why?In some area there is a lack of radiologists.
Sometime it could be financially accurate to have only one radiologist on duty for several radiological facilities.
Eg: A contract with TeleRadiology Service Provider Company(Our Company) with any Hospital or Diasnostic center in India or even at International Levels - Daytime Reporting or Night Hawks.
Access to specialized expertise.

The projectsThe projects
Send examinations to “on duty” radiologist Home.
One radiologist on duty for all Multiple hospitals.
Ability to send examination (radiology images – like x-rays, CT scan, MRI or any patient data) from one hospital to another or to reporting center directly from daily used working tools.
Simplicity of use.Security.

Each hospital department will have its own network with nodal point in the main hospital.
All four networks will be federated on Main Server.
Main server will be able to:Give access to images in the DMZ,Import images in the local PACS,Send images to the right specialist “on duty” home or Our center for reporting.
