Intrinsic and tomographic evaluation tests on the Siemens e.cam® Signature Series Single Photon Emission Computed Tomography (SPECT) system were conducted to ensure that it meets the specification required by the user and the capabilities claimed by the manufacturer after installation. The tests were performed according to National Electrical Manufacturers Association protocols and various measuring instrument and point sources containing 99 m-Tc were used. Intrinsic tests performed include intrinsic flood uniformity, intrinsic count rate performance in air and intrinsic energy resolution. Whole body scanning, SPECT resolution without scatter, SPECT resolution with inserts, SPECT uniformity and center of rotation were also evaluated. The intrinsic count rate performance measured was 300kcps as against manufactures' specification of 310 kcps, intrinsic energy resolution was 9.31% whiles manufacturers' specification was # 9.9% and center of rotation specification is that Max. X-Min. X< 1 pixel and RMS < 0.5 whiles values measured was 0.254 and 0.10 for LEAP and 0.092 and 0.083 for LEHR collimators. The evaluation confirm that the SPECT system met the requirements for clinical medical imagine and also the values obtained could be used as baseline data for future quality control. © Maxwell Scientific Organization, 2011.
