Summary: | In a detector arrangement for a medical diagnosis apparatus as well as a medical imaging diagnostic method, radiation quanta striking a detector are detected and evaluated with spatial resolution. The use of collimators is thereby omitted, such that radiation quanta that strike at a non-perpendicular angle to the detector are also evaluated. For spatial resolution of the origin of the radiation quantum, the spatial distribution of sensor elements of the detector that emit a signal upon incidence of a radiation quantum is evaluated. A higher efficiency of the radiation evaluation is enabled and, particularly in nuclear medical diagnostic methods, the radiation exposure of the patient can be distinctly reduced. |
