Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Biophysics Summary: Background: There are various physical factors that limit the quality of the Single Photon Emission Computed Tomography (SPECT) images such as number of frames per projection, number of projections per scan and time per projection in gated myocardial SPECT scan. Objectives: The aim of the present work was to evaluate physical acquisition parameters affecting the cardiac imaging to optimize the patient{u2019}s examination time and image quality that are acquired with the gamma camera and workers radiation protection (through reducing time of radiation exposure) in cardiac SPECT facility using cardiac functional parameters ejection fraction (EF), end diastole volume (EDV), end systole volume (ESV) and total perfusion defect (TPD). RESULTS: There was insignificant difference in the EF, EDV, ESV and TPD between the different groups concerning the number of frames per projection, number of projections per scan and time per projection. CONCLUSION: The reduction of scan time to half or the number of projections per scan to half or increasing the number of frames per scan from 8 to 16 at the same duration has insignificant effect in the cardiac functional parameters used with gated SPECT scan.
