The development of picture archiving and communications systems (PACS) for medical applications can be regarded as a challenging field in medical informatics. Since 1982, several projects have been started into this direction worldwide. The Dutch IMAGIS (Image Information System) project, started in 1984, is one of them. Within this project, a top-down design strategy is chosen, with the following first steps: (1) A thorough information analysis for a Radiology Department, in which both qualitative and quantitative aspects are included. Such an analysis can be used to estimate the workload on a future PACS system. (2) The construction of a flexible performance prediction tool, based on discrete even simulation. Such a tool can be used to predict the performance of a certain computer system configuration under a certain workload. Based on the information analysis, and using the performance prediction tool, a PACS system is drafted for the thorax section of the Diagnostic Radiology Department of the Leiden University Hospital. In this first design attempt, the assumption was made that current working procedures concerning images will be maintained as much as possible.
医学应用中的图像存档与通信系统（PACS）的开发可被视为医学信息学中一个具有挑战性的领域。自1982年以来，全球范围内已启动了多个朝此方向开展的项目。1984年启动的荷兰IMAGIS（图像信息系统）项目就是其中之一。在该项目中，采用了自上而下的设计策略，具体包括以下首要步骤：（1）对放射科进行全面的信息分析，涵盖定性和定量两方面。这样的分析可用于估算未来PACS系统的工作量。（2）基于离散事件模拟构建一个灵活的性能预测工具。该工具可用于预测特定工作负载下某种计算机系统配置的性能。基于信息分析并使用性能预测工具，为莱顿大学医院诊断放射科的胸部部分设计了一个PACS系统。在这首次设计尝试中，假定尽可能维持当前有关图像的工作流程。
