Abstract
Our PC-based upgrading system for acquisition of images from analogue gamma cameras will be extended to the semidigital cameras and to the development of tridimensional read-out system for locally deposited ionisation from single or double scattered gamma ray in a thick semiconductor detector. The later is important for the development of Compton gamma camera based on our idea of thick silicium locally sensitive detector system. Such camera would drastically improve the sensitivity (more than 100 times), energy (3-5 times) and spatial resolution (2 times) , no collimator and no detector rotation, and it would be mechanically simple and very light (for 100 times ). GAMMA-PF acquisition and clinical software will be upgraded from DOS to Windows operational system, development of converters for image data from/to international standards (DICOM, INTERFILE, PIP, ACR/NEMA¸ ANALYSE), development of graphic station for display and analysis of tomographic images, geometrical scaling, registration and fusion of tomographic data from one to another set from functional imaging modalities (SPECT, PET) to morphological (MR, CT) for the improvement of diagnostic accuracy. By simultaneous buildup of intranet computer network it will be possible to equip each clinical department with the proposed graphical station for communication with "sof"t diagnostic report instead of film and paper report, archiving, computer planing of therapeutic procedures and follow-up of patient disease.
