TOMOGRAPHIC DEVICE AND METHOD WITH TRANSLATIONAL MOVEMENT BETWEEN OBJECT AND DETECTOR

摘要

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.
