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.
