The objective of this project is to design, build and evaluate a compact and mobile gamma and positron imaging camera. This imaging device has several advantages over conventional systems 1 greater flexibility in positioning with respect to the target organ for improved spatial resolution and sensitivity, 2 the ability to image patients who cannot be transported to a radiology suite, 3 the potential for improved cost effectiveness for organ-specific imaging tasks compared with larger, general purpose imaging systems. Simulation studies have demonstrated the potential image quality that can be produced with this device operating in either dual gamma, coincidence mode or single gamma mode. The construction of the system gantry has been completed and the mechanical testing is nearly completed. The gantry has demonstrated the ability to position the detectors, with respect to the patient on an intensive care unit bed, as the design specified. Detector design and fabrication is nearly completed. Images have been obtained from a small field of view, prototype detector, which demonstrated satisfactory performance. Fast data acquisition electronics for high count rate capability have been built and tested.
