The OSIRIS User Interface for Manipulating Medical Images

This paper describes the OSIRIS project developed at the University Hospital of Geneva. Its goal is the design of a software to read medical images files stored in the PAPYRUS format and, more important, to display and analyse them in a window based user interface environment. This software is a main part of the PACS project conducted at the Geneva Hospital. OSIRIS has been designed to work on a wide variety of workstations and window systems (Unix systems with Xll and OSF/Motif and Macintoshs). It provides the traditional modes of visualisation (zoom in, zoom out, invert, etc) and allows more specific manipulations such as a movie mode, filters, measure of distances, modification of the color lookup table. OSIRIS allows to display a second window containing the image interpretation report, a window containing some study information and allows to add annotations to an image.
