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.

Boston experimentation: a contract with an Israeli and an Asian Hospitals to have only daytime reading.

Each département will have its own network with nodal point in the main hospital at the préfecture (main town of the département).

All four networks will be federated on Clermont-Ferrand University Hospital (CHU).

At the CHU a 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 for advice.
