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, for example, intensive care patients, and 3 the potential for greater cost effectiveness for organ-specific imaging tasks, compared with larger, general purpose imaging systems. The complete imaging system was assembled at the University of Florida and evaluation studies were performed. Basic performance measures including spatial resolution, system sensitivity, and count rate capability were performed and met design specifications. Reconstructed image quality was assessed using anthropomorphic phantoms. In the initial clinical evaluation, the images from the mobile system compared favorably with images obtained from the same patients using conventional imaging systems.
