Abstract

Performance evaluation tests on Siemens e.camR Signature Series Single Photon Emission Computed Tomogra-phy (SPECT) System at Korle-Bu Teaching Hospital (Ghana) were conducted for compliance with Manufactur-erfs specifications and usersf requirements. The tests were performed according to National Electrical Manufac-turers Association protocols, and different measuring instruments and phantoms containing 99m-Tc were used. Extrinsic uniformity, System energy resolution, System spatial resolution (without scattering), Detector shield leakage and System planar sensitivity were evaluated. The System energy resolution measured was 9.38 % as against manufacturersf specification of . 9.9 %, Planar sensitivity value measured was 232.92 c/min/mCi while manufacturersf specification was 202 c/min/mCi, and Detector shield leakage values measured were 0.001 %, 0.022 % and 0.025 % against an accepted value of < 1 %. The performance evaluation confirmed that the Syst-em met requirements for clinical nuclear medicine imaging, and the values could be used as database for future quality control measurements.
