Performance evaluation tests on Siemens e.cam(R) Signature Series Single Photon Emission Computed Tomography (SPECT)System at Korle-Bu Teaching Hospital (Ghana) were conducted for compliance with Manufacturer’s specifications and user’s requirements. The tests were performed according to National Electrical Manufacturer’s 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 manufacturer’s specification of ≤ 9.9 %, Planar sensitivity value measured was 232.92 c/min/mCi while manufacturers’ specification was 202 c/min/mCi, and detector shield leakage values measured were 0.001 %, 0.002 % and 0.025 % against an accepted value of < 1 %. The performance evaluation confirmed that the system met requirements for clinical nuclear medicine imaging, and the values could be used as database for future quality control measurements. (au)
