Even though a client hospital has made an urgent image-interpretation request, if a designated radiologist is out of an image-interpretation center, a data center transfers the request to a portable terminal of the radiologist. Upon receiving the urgent request, the radiologist accesses the data center to download an image to be interpreted.

The detailed image has higher resolution than the whole image because it is not subjected to the data amount reduction process. The radiologist makes a medical report with observing the image by the portable terminal and uploads it to the data center.
