AB Commercially available single photon emission computed tomography (SPECT) cameras require both new calibration and very careful routine quality control procedures. These procedures must be performed properly and regularly to produce artifact-free images. Calibration procedures include field uniformity, center of rotation, pixel size, and camera alignment. Of these, field uniformity is the most important because nonuniformities have a greater effect on tomographic images than on planar images. Calibration procedures for all these SPECT parameters are presented in detail as are quality control procedures that will ensure artifact-free, clinically useful images.
