Fig. 1

Schematic cross section of the arrangement of the detectors of the new two-detector SPECT system (2DT-Scanner) (a) and a standard three-detector system (3DT-Scanner) (b). The surface of each stationary detector head, shown here as a square, has a size of 47.2 cm × 59.5 cm and consists of 9.5-mm-thick NaI(Tl) crystals. Collimators’ inner diameter is 45.0 mm and centre field of view (CFOV) counts 12.0 mm diameter by 7.0 mm length
