The principles of nuclear medicine studies are based on the assessment of radionuclidic distribution in different parts of a given organ after in vivo administration of a radiopharmaceutical to distinguish between the normal and abnormal tissues. Such assessment of radionuclide distribution is performed by imaging systems that primarily use NaI(Tl) detectors and the associated electronics described in the previous chapter. There are two major imaging systems: rectilinear scanners and scintillation cameras. Rectilinear scanners have been almost phased out in nuclear medicine, whereas scintillation cameras are the equipment of choice for routine use in nuclear medicine imaging. Because of their demise from practical use in nuclear medicine, rectilinear scanners will be only briefly described.
