title: [Image-transmission using 64 kbps-ISDN (Integrated Services Digital Network) and mini-PACS].
abstract: We carried out the image-transmission using 64kbps-ISDN between two image workstations (IWS) of mini-PACS installed at the Department of Radiology, Osaka Teishin Hospital and the Kashiwa Works, Hitachi Medical Corporation. The distance between Osaka and Kashiwa is about 600 km. The subtraction of two images before and after transmission revealed no change of the data of the image during transmission. For 1/2 compression image, the times of image-transmission of 256 x 256, 320 x 320 and 512 x 512 matrix were 9, 17 and 33 second, respectively. The efficiency of image-transmission was about 80%. Using ISDN, we can make an accurate, rapid and cheap image-transmission.
