Design of medical tele-consultation su

摘要

Abstract: We introduce a radiologic tele-consultation support system based on an inter-hospital network. The system consists of an image database system, a super-high-definition (SHD) imaging system, a video conferencing system and a high-speed network. The SHD imaging system displays 2048 (H) $MUL 2048 (V) $MUL 8 bit radiological images with sufficient image quality to allow diagnosis. The network connects six facilities including Keio University Hospital at 135 Mbps, and Seiransou Hospital (B) at 6Mbps to the database in NTT Research and Development Center. The system was developed in three stages. First, the system was not designed for just consultation, but also for tele-medicine/tele-radiology; doctors in different hospitals can control their systems independently during a consultation. The first stage system, tele-consultation was suspended until the completion of image transmission at both sites, since image transmission occurs only when requested. The second stage added an image pre-loading function in order to eliminate the time-lag of image transmission. Pre-loading the images was effective but exposed some shortcoming in terms of collaboration. Finally, we implemented several functions for collaboration such as synchronization of image-display and pointer indications on the image. The final system fulfills all requirements and consultations proceeded smoothly. !4
