The standard SPECT phantom is used for the determination of the tomographic specifications of SPECT systems. The phantom consists of a circular acrylic vessel of 200 mm diameter and 214 mm height including various test inserts. Three parameters can be checked simultaneously during one measuring cycle: The tomographic resolution is tested by a number of acrylic rods of different diameters located in six phantom sections. The rod diameters are 4.0 / 6.0 / 8.0 / 10.0 / 12.0 and 15.0 mm. The tomographic contrast is tested by six fully acrylic spheres with diameters of 9.5 / 14.4 / 19.0 / 25.4 / 31.8 and 38.1 mm, simulating cold spots.
