Performance evaluation of 4D reconstruction methods for gated cardiac single photon emission computed tomography in obese patients

Abstract: The purpose of this study is to evaluate 4D reconstruction methods for the processing of gated cardiac single photon emission computed tomography (SPECT) images from obese patients.Clinical gated SPECT projection data were reconstructed using the ordered-subsets expectationmaximization (OS-EM) IntroductionMyocardial SPECT imaging is frequently the imaging technique of choice used to visualize perfusion defects of the heart. Cardiac gating adds a vital dimension to myocardial imaging, enabling the diagnostic… Show more
