Paper Abstract

When studying the functions to be supplied by a PACS the need for a link with the HIS/RIS turns out to necessary for two classes of reasons: - the first class deals with the need to supply as much clinical information at the workstations as possible. Whether this information is stored within the HIS/RIS should be transparant to the user. - modelling and simulation of PACS gives evidence that thetraffic load in a PACS can only be handled adequately when the image management system can take into account patient flow and patient medical story. As typical example can be mentioned prefetching algorithms that take care of activation of images from the archive before they are actually needed. The activation process is controlled by events in the hospital that indicate an increased probability that these images will be needed. The first class of reasons lead in general only to use of data that in principle can just be presented on the screen of the workstation. The PACS does not need to be aware of the meaning of the data: no common understanding is necessary. So just data can be transfered that will be presented in a transparant way. The second class of reasons deals with data from the HIS/RIS that should be understood by the PACS to be able to take the required action. So the meaning of the data is to be known. In this second class we have to deal with exchange of information while for the first class exchange just data is sufficient. Since the concepts of PACS and HIS are to a large extent similar it is not evident to which of the two certain functions will be assigned. This assignment of functions is considered and some suggestions for implementation of a link between PACS and HIS/RIS are given.
