Image transmission using ISDN is not yet popular in Japan, but the number of ISDN terminals is rapidly increasing since 1991. We have two systems for image transmission using ISDN. One system uses an image workstation of the mini PACS. With this system, an image can be directly input from CT or MR to the workstation, and transmitted without errors. This system is very expensive. The format of images is the original one, and the data can be transmitted between workstations. The other system is the ISDN videophone. Images are input to the videophone through a CCD camera. The quality of the image is not high. However, this system is cheap and easy to use. In the near future, the videophone will be widely distributed, and will be used also for the transmission of medical images.
在日本，使用综合业务数字网（ISDN）进行图像传输尚未普及，但自1991年以来，ISDN终端的数量正在迅速增加。我们有两种使用ISDN进行图像传输的系统。一种系统使用小型图像存档与通信系统（mini PACS）的图像工作站。通过该系统，图像可以直接从CT或MR输入到工作站，并毫无差错地传输。该系统非常昂贵。图像格式是原始格式，数据可以在工作站之间传输。另一种系统是ISDN可视电话。图像通过电荷耦合器件（CCD）相机输入到可视电话中。图像质量不高。然而，该系统价格便宜且易于使用。在不久的将来，可视电话将得到广泛应用，也将用于医学图像的传输。
