Title

Review on Recent Developments in Collimators of Single Photon Emission Computed Tomography Imaging

Pages

  125-133

Abstract

 In Single Photon Emission Computed Tomography (SPECT), Collimator selection, optimization, and also geometric calibration have a major impact on the acquired Image Quality and also on an accurate detectability and diagnosis. The Collimator optimization phenomena consider some parameters such as field of view, Resolution, Sensitivity, Resolution at depth, septal thickness and penetration for a specific application task. While the parallel hole Collimator is usually used in SPECT and planar imaging but due to the limited solid angle covered by the Collimator, the system Sensitivity and Resolution were highly reduced. Meanwhile, other types of Collimators such as pin-hole, multi-pin-hole, slant and slit-slat Collimators were introduced with a trade-off between Sensitivity and Resolution. This article reviews improvements on Collimators also by considering the geometry and geometric calibration methods for improving the Image Quality in Single Photon Emission Computed Tomography.
