The Department of Radiology of the Shinshu University Hospital is presently in the process of developing a new type of mini-PACS with a hybrid architecture consisting of a video and a digital image archiving network. The video block consists of a server station with a video write-once optical disk (LD) and three workstations which are connected to two ultrasound imaging devices and an MRI device. The video images from any of these imaging devices are transferred immediately onto an LD. The examiner can observe the archived images immediately without any interruption of the examination. The image transmission time, including the record and play-back, is within 3 s. The digital block consists of a personal computer server and various workstations linked to the ETHERNET. This digital system supports database management, and archives digital images. This prototype system was used for daily clinical examinations from February 1989 to January 1990 and 31,366 images from 1561 patients were stored on the video disk. This one year experience suggests that a hybrid mini-PACS system is practical for total image archiving when the image matrix is less than 512 x 512 and selected digital image archiving.
信州大学医院放射科目前正在开发一种新型的小型PACS，其采用由视频和数字图像存档网络组成的混合架构。视频模块由一个带有一次写入式视频光盘（LD）的服务器站和三个工作站组成，这三个工作站连接到两台超声成像设备和一台MRI设备。来自这些成像设备中任何一台的视频图像会立即传输到LD上。检查人员可以立即观察存档图像，而不会中断检查。包括记录和回放在内的图像传输时间在3秒以内。数字模块由一台个人计算机服务器和连接到以太网的各种工作站组成。这个数字系统支持数据库管理，并存档数字图像。这个原型系统在1989年2月至1990年1月期间用于日常临床检查，1561名患者的31366张图像存储在视频磁盘上。这一年的经验表明，当图像矩阵小于512×512且选择数字图像存档时，混合小型PACS系统对于全图像存档是实用的。
