Abstract

The spatial resolution in a reconstructed SPECT image is obviously influenced by the intrinsic resolution of the detector, but it is not generally recognized that the photon-counting efficiency of SPECT systems is also determined by the intrinsic resolution. In this paper we attempt to demonstrate that improvements in detector resolution can lead to both improved spatial resolution in the image and improved counting efficiency compared to conventional systems. In this paper we report simulation studies that demonstrate the image quality that is attainable with such detectors. Reconstructions were performed using an iterative search algorithm on a custom designed parallel computer. We found a resolution close to 2 mm on the reconstructed images obtained from these computer simulations with clinically reasonable exposure times.
