ABSTRACT:
A tomography device, particularly for single photon emission computed tomography (SPECT), comprises a multi-pinhole collimator and a detector for detecting gamma quanta or photons that penetrate the multi-pinhole collimator. In a tomographic method using the device, the distance between the object and the multi-pinhole collimator is selected to be smaller than the distance between the multi-pinhole collimator and the surface of the detector.
