ABSTRACT:
A single-photon emission computed tomography (SPECT) apparatus for detecting gamma rays emitted from a radioisotope given to a body to be examined, including three focus collimators and corresponding detectors arranged at 120.degree. intervals and each capable of rotating 120.degree. around the body for providing detection data; a processor for processing said detection data to produce reconstruction data corresponding to a density distribution tomographic image of the radioisotope in the body; and holding mechanisms for positioning a compensation radioisotope at the focus point of each focus collimator on a structure which rotates together with each focus collimator and corresponding detector upon rotation of each focus collimator and corresponding detector around the body.
