The advantages to be expected of full-scale PACS implementation are widely described in the literature. In the decision to introduce such systems, costs will also play an important part. The benefits to be achieved should at least outbalance the costs. In this paper the set-up of a software package for cost assessment is described. The configuration requirements have to be determined based on the workload of the radiology department and a PACS model using results of simulation studies. Of course additional user requirements are important input parameters (e.g. number of workstations, screen resolution, etc.). Data on costs of the various configuration components and the expected future trends in these costs will be used to estimate the costs of a specific PACS configuration as a function of time. Savings to be achieved in the various categories of resources will be input (again with their trends) to lead to an overview of the total savings to be expected. The package will result in a graph of the net annual costs as a function of the timing of PACS introduction. In the package a critique module is foreseen that checks whether the data fed into the system are of reasonable agreement with expert opinions.
文献中广泛描述了全面实施PACS有望带来的优势。在决定引入此类系统时，成本也将起到重要作用。所实现的效益应至少超过成本。本文描述了一个用于成本评估的软件包的设置。必须根据放射科的工作量以及使用模拟研究结果的PACS模型来确定配置要求。当然，额外的用户需求也是重要的输入参数（例如工作站数量、屏幕分辨率等）。各种配置组件的成本数据以及这些成本的预期未来趋势将用于估计特定PACS配置随时间变化的成本。将输入各类资源预期实现的节省（同样包括其趋势），以得出预期总节省的概述。该软件包将生成一张净年度成本与PACS引入时间的函数关系图。软件包中设有一个评估模块，用于检查输入系统的数据是否与专家意见合理一致。
