Original article The RETAIN project: dicom teleradiology over an ATM-based network

摘要: Abstract. The RETAIN project (Radiological Exam-inations Transfer on an ATM Integrated Network)has aimed at testing videoconferencing and DICOMimage transfers to get advice about difficult radiolog-ical cases over asynchronous transfer mode(ATM)-based network, which affords a more com-fortable interface than narrow-band networks al-lows exchange of complete image series using the DI-COM format studies. For this purpose, experi-mental network was applied between six uni-versity hospitals in four different countries. An as-sessment functionalities system per-formed by means log-file analysis, video recordingof sessions forms filled out participantsat end each session. Questionnaires were an-swered users bringout perspectives utilisation added value.
