title: [High-resolution teleradiology system based on ISDN and small computer].
abstract: A high-speed, high-resolution teleradiology system based on the Integrated Services Digital Network (ISDN) is described. The LAN at Saku Central Hospital and the Radiological Department at Shinshu University Hospital (60 km) are interfaced to a Macintosh computer with an image digitizer, interactive display, and network interface. The transmission time for a digitized high-resolution radiographic image with 4.39 megabytes was 358 seconds using a 128 kbps (kilobit-per-second) channel (B1 + B2), and the mean transmission rate was 98.1 kbps. Teleradiology conference is also available using this system. Radiologists can observe the same high-resolution images on the CRT screen simultaneously at two different remote hospitals, indicating a point of interest on the image by means of a mouse cursor. Graphical data of interest to the radiologists are also transmitted and displayed on the CRT.
