There are a number of institutions and equipment manufacturers developing PAC systems or components of such systems. Much effort at our medical center has gone into the development of a workstation for radiologists, and this has been one of the primary devices built by others as well. As a result, diagnostic viewing stations are in operation and their designs are being refined. We have begun to examine the problem posed by the large number of viewing devices which may be required to satisfy the needs of the physicians and clinicians who refer patients to Radiology and want to see the studies which have been performed. Currently, this function is supported by a large number of film viewboxes and alternators both in the Radiology Department and in other hospital locations. It would be prohibitively expensive to replace all such viewing devices with diagnostic workstations, so we have considered the possible alternatives. We call this class of electronic viewing device the image viewstation. The goal of the design of an image viewstation is to satisfy user requirements at reasonable cost. However, we also need to design a device which can be interfaced to a network easily. This has led us to consider systems with both analog and digital image transmission. The former has the advantage of speed, the latter the desired full dynamic range and resolution. To a large extent, the method chosen is network dependent. This paper discusses the designs we have envisioned, the reasons we have chosen them, and how they might be implemented.
