医学影像学信息系统工作站配置方案的探讨

目的：探讨适合国情的医学影像学信息系统工作站配置方案及实现方式。方法：工作站逻辑上分别医学影像存储与传输系统（PACS）工作站和放射学信息系统（RIS）工作站。PACS工作站包括CT和MR影像诊断、常规X线影像诊断，以及高分辨灰阶显示等3类工作站组成；RIS工作站则根据其用途分为诊断报告、登录、报告打印与分发、管理等多种功能类别。结果：影像诊断报告工作站采用单机双屏构型，物理地集成PACS和RIS的影像诊断过程的操作。CT、MR等低像素影像诊断过程配置对角线17in(1in=2.54cm）彩色显示顺作为操作界面，常规X线影像诊断操作则采用21i彩色或灰阶肖像式显示器配置，对于未涉及影像操作的工作站类型，如IRS登录、报告分发、管理等，全部采用普通PC机实现。结论：满足医学影像诊断的基本需求并符合节约投资的要求是进行医学影像学信息系统工作站规划所遵循的基本原则，单机双显配置可以成为医学影像学诊断工作站构型设计的首选方案。

The scheme and implementing of workstation configuration for medical imaging information system

Objective To discuss the scheme and implementing for workstation configuration of medical imaging information system which would be adapted to the practice situation of China. Methods The workstations were logically divided into PACS workstations and RIS workstations, the former applied to three kinds of diagnostic practice: the small matrix images, large matrix images, and high resolution grayscale display application, and the latter consisted of many different models which depended upon the usage and function process. Results A dual screen configuration for image diagnostic workstation integrated the image viewing and reporting procedure physically, while the small matrix images as CT or MR were operated on 17 in (1 in =2.54 cm) color monitors, the conventional X ray diagnostic procedure was implemented based on 21 in color monitors or portrait format grayscale 2 K by 2.5 K monitors. All other RIS workstations not involved in image process were set up with a common PC configuration. Conclusion The essential principle for designing a workstation scheme of medical imaging information system should satisfy the basic requirements of medical image diagnosis and fit into the available investment situation.
