The invention relates to a device for carrying out a tomographic method, in particular for carrying out single-photon tomography, with at least one multi-hole collimator and at least one detector, for recording photons which pass through the multi-hole collimator. The above is characterised in comprising means which permit a relative translational movement between an object under investigation and the detector(s) with a positional accuracy of less than 1 millimeter. The relative positional change between object and detector(s) during the execution of the method is taken into account in the subsequent reconstruction method to an accuracy of less than 1 mm, in particular, less than 0.1 mm. A reconstruction method is used for the above which takes into account the positional and angular information between object and detector. Said method may be controlled by and carried out on a current PC.

Tomographic device and method with translational movement between object and detector

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.
