Teleconference system composed of Super High Definition system and B-ISDN

Abstract

We established a teleconference system for cardiovascular disease composed of Super High Definition (2048pixel^*2048line^*60frame/s) Image system and broadband ISDN. And we held a teleconference between Osaka university and Kyoto university. For this experiment we selected about 1000 images (containning moving images) taken from 1 patient with ischemic heart disease, and digitized them and made 243 frames. These images were evaluated by 21 cardiac specialists and proved to be sufficient for making diagnosis. We prepared a graphical user interface (GUI) for image retrieval based on the medical events and modalities. In addition we prepared pointing device on the display monitor and TV phone for effective conference. Images prefetched in the both frame memorys can be selected and displayed on the monitor by opreating the GUI from both side.
