Performance Evaluation of the Nuclear Medicine Imaging Modalities at NINMAS
Keywords:Performance Evaluation, SPECT System, Quality Control, CT Number, Resolution.
Performance evaluation of the imaging systems of nuclear medicine have been checked and compared with the previous data which were collected at the time of acceptance testing at the National Institute of Nuclear Medicine & Allied Sciences (NINMAS). Performance measurements that have been carried out for the SPECT and SPECT-CT system recently were according to NEMA NU 2-2012 standard and IAEA Human Health Series No.1. Phantoms required for these tests to be performed were supplied by the vendors. Performance tests checked for the SPECT system were intrinsic flood field uniformity, intrinsic spatial resolution, center of rotation (COR), offset and alignment of axes, sensitivity and total performance test. The CT Phantom tests have been carried out for the visual inspection of resolution, contrast, noise and uniformity of the CT system. In these studies, performance evaluations of nuclear medicine imaging modalities including SYMBIA Evo Excel Dual Head SPECT Scanners, SYMBIA T16 SPECT-CT System and Nucline TH-45 Single Head Gamma Camera for Thyroid have been done to ensure the quality of service given to the patients. Performance measurements of these imaging modalities have shown satisfactory image quality. All data were compared with the acceptance testing data which were carried out during installation at the institute.
