title: Teleradiology at Gunma University Hospital.
abstract: Using NEC MediFile 1000 and the public telephone system, the Department of Radiology of Gunma University Hospital and Saitama Medical School deliver image diagnosis to fellow clinicians and affiliated hospitals. The system consists of digitizing, filing, processing, retrieving and archiving units for radiographs and documents. Images were digitized by CCD and filed in 2 Gbyte double sided optical disk, which can accommodate 500 sheets of 14 x 17 films on 1500 of the smallest size slats without data compression. Image resolution was evaluated by ROC curve using multiple pulmonary nodules. The time taken for image transfer over 24 km was tested with various film sizes, image varieties and data compression rates.
