WebNov 3, 2024 · 1 INTRODUCTION. Consistent quality control (QC) is key to maintaining image quality in a nuclear medicine department. Routine assessment of a gamma camera’s energy peaking, planar intrinsic and extrinsic uniformity, intrinsic and extrinsic spatial resolution, and spatial linearity have been recommended by accrediting bodies such as the American … WebThe application of absolute quantification in SPECT/CT has seen increased interest in the context of radionuclide therapies where patient-specific dosimetry is a requirement within the European Union (EU) legislation. However, the translation of this technique to diagnostic nuclear medicine outside this setting is rather slow. Clinical research has, in some … is deck 9 good on the arvia
