Quality Control Tests of SPECT- CT

The one of the aim of nuclear medicine is diagnosis of an abnormal metabolic activities in target organs. In a routine nuclear medicine imaging procedure, a radiopharmaceutical is used. Radiopharmaceutical’s radionuclide part emits gamma radiation. This radiation is dedected by Gamma Camera or Single Photon Emission Computed Tomography (SPECT). A computed tomography (CT) device was added to the SPECT(SPECT- CT). To combine anatomical images. Image quality of this device is important for accurate diagnosis and treatment of diseases. By means of quality control tests, performance changes of device are dedected. A various quality control parameters such as uniformity, sensivity, resolution, linearity have been developed for Gamma cameras, SPECT. Quality control test results are should be verify by comparing acceptable results. In this study, quality control tests of SPECT-CT are performed as proposed by the National Electrical Manufacturers Association ( NEMA) and it was aimed to investigate some correction methods
