1 May 1996 Distributed file management for remote clinical image-viewing stations
Author Affiliations +
The Geneva PACS is based on a distributed architecture, with different archive servers used to store all the image files produced by digital imaging modalities. Images can then be visualized on different display stations with the Osiris software. Image visualization require to have the image file physically present on the local station. Thus, images must be transferred from archive servers to local display stations in an acceptable way, which means fast and user friendly where the notion of file must be hidden to users. The transfer of image files is done according to different schemes including prefetching and direct image selection. Prefetching allows the retrieval of previous studies of a patient in advance. A direct image selection is also provided in order to retrieve images on request. When images are transferred locally on the display station, they are stored in Papyrus files, each file containing a set of images. File names are used by the Osiris viewing software to open image sequences. But file names alone are not explicit enough to properly describe the content of the file. A specific utility has been developed to present a list of patients, and for each patient a list of exams which can be selected and automatically displayed. The system has been successfully tested in different clinical environments. It will be soon extended on a hospital wide basis.
