摘要： The invention relates to a tomography device and method, particularly for single photon emission computed tomography (SPECT). The device for carrying out a tomography method, especially for carrying out a single photon tomography, comprises a multi-pinhole collimator and a detector for detecting gamma quanta or photons that penetrate the multi pinhole collimator. According to the device for carrying out the tomographic method, the distance beteween 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. The invention provides a device and a method with which the desired result can be achieved with a high spatial resolution and sensitivity.
