Abstract

The design considerations for a megavoltage imager based on the distribution of pair production events in tissues are explored. Optical scintillating fibers utilizing electronic collimation are used to detect the 0.511 MeV annihilation radiation from the pair production events. The resolution, efficiency, and signal-to-noise ratio characteristics of this imaging modality are discussed and compared to conventional computed tomography (CT) and positron emission tomography (PET) imagers. A proof of principle small animal imager experiment is discussed.
