Picture archiving and communication systems (PACS) are expected to convert film-based radiology into a computer-based digital environment, with associated cost savings and improved physician communication. The digital workstation will be used by physicians to display these “soft-copy” images; however, difficult technical challenges must be met for the workstation to compete successfully with the familiar viewbox. Issues relating to image perception and the impact on physicians’ practice must be carefully considered. The spatial and contrast resolutions required vary according to imaging modality, type of procedure, and class of user. Rule-based software allows simple physician interaction and speeds image display. A consensus appears to be emerging concerning the requirements for the PACS workstation. Standards such as the American College of Radiology/National Electrical Manufacturers’ Association Digital Imaging and Communication Standard are facilitating commercial applications. Yet much careful study is needed before PACS workstations will be fully integrated into radiology departments.
图像存档与通信系统(PACS)有望将基于胶片的放射学转变为基于计算机的数字环境,从而节省相关成本并改善医生之间的沟通。医生将使用数字工作站来显示这些“软拷贝”图像;然而,要使该工作站成功与熟悉的观片灯竞争,必须应对艰巨的技术挑战。与图像感知以及对医生实践的影响相关的问题必须仔细加以考虑。所需的空间分辨率和对比度分辨率会根据成像方式、检查类型和用户类别而有所不同。基于规则的软件使医生能够进行简单的交互并加快图像显示速度。关于PACS工作站的要求似乎正在形成一种共识。诸如美国放射学会/美国国家电气制造商协会数字成像和通信标准之类的标准正在推动商业应用。不过,在PACS工作站完全融入放射科之前,还需要进行大量细致的研究。
