The goal of this project is to construct a functioning compact positron tomograph, whose geometry is optimized for detecting prostate tumors with molecular tracers such as 11Ccholine carbon-11 choline, in order to confirm the presence, absence or progression of prostate cancer. When completed, the camera will consist of two banks of detectors mounted in a gantry. The bottom bank is fixed below the patient bed, and the top bank moves upward for patient access and downward for maximum sensitivity. During the first 22 months of funding, we have optimized and completed the tomograph design, fabricated all gantry components and nearly completed construction of the gantry and electronics housing, acquired and tested all detector modules and electronics, developed an iterative reconstruction algorithm for the special camera geometry, and simulated the reconstruction of realistic Monte Carlo data. Progress is on schedule.
