Design studies of a CZT-based detector combined with a pixel-geometry-matching collimator for SPECT imaging

Single Photon Emission Computed Tomography (SPECT) suffers limited efficiency due to the need for collimators. Collimator properties largely decide the data statistics and image quality. Various materials and configurations of collimators have been investigated in many years. The main thrust of our...
