We have developed and implemented a teleradiology system for radiologic images between Tokyo University Main Hospital and Mejirodai Annex. The basic system is composed of an image acquisition unit and an image transmitting unit on both sites.The image acquisition unit that we named MIG (medical Imaging Gateway) is composed of a CCD digital still camera, a Toshiba personal computer J3100, and a RGB monitor. Films on a lightbox are taken by the digital still camera, whose image resolution is more than 400 lines (both vertical and horizontal) with 8 bit (256) gradations.The image transmitting unit is composed of a 9600 bps modem and two public telephone lines on each site. The two site is 5 Km apart. Images are sent to the other site before consultation and conference. The time for transmission is about 4 minutes per an image. Commands to control display, such as paging and ROI pointing are sent from host to local site by the telephone line. Therefore what is happening on local site display is exactly the same as the display on the host site. Discussions are made through usual telephone line.

我们开发并实施了东京大学本部医院和Mejirodai附属医院之间的放射图像远程放射系统。基本系统由两个站点的图像采集单元和图像传输单元组成，图像采集单元由CCD数码相机、东芝J3100个人计算机和RGB显示器组成，我们将其命名为“医学成像网关”（Medical Imaging Gateway）。灯箱上的胶片由数码相机拍摄，其图像分辨率大于400线（垂直和水平），8位（256）灰度级，图像传输单元由一个9600bps调制解调器和两条公用电话线组成。这两个网站相距5公里。图像在咨询和会议之前发送到其他网站。每幅图像的传输时间约为4分钟。控制显示的命令，如寻呼和ROI指向，通过电话线从主机发送到本地站点。因此，本地站点显示器上发生的情况与主机站点上的显示器完全相同。讨论通过普通电话线进行。
