ABSTRACT:
A single photon emission computed tomography (SPECT) system for producing transaxial images in a plurality of transaxial planes through a body. The SPECT system includes a detector system with an in-plane spatial resolution that is determined by the in-plane spatial resolution of collimator modules disposed in a ring around the body to be imaged. Photon detectors and related circuits merely determine a position in a photon detector matrix having discrete azimuthal positions that correspond to the physical size of a collimator module. Axial spatial resolution or slice thickness for the detector system is determined either by collimator modules or by collimator modules in conjunction with the intrinsic resolution of the photon detectors.
