Patent ID: 8030617

Claim:
A method for detecting radiation with angular resolution comprising: providing a detector assembly, said detector assembly comprising at least one detector element having a front face and a rear face, wherein a space between the front face and the rear face of the detector element is filled with a plurality of regions of a first detector material and at least one region of a second detector material, and each region connects the front face to the rear face of the detector element, and wherein an energy deposition takes place in at least the regions of the first detector material as a function of an angle of incidence of the radiation on the detector element; recording a spectrum of the energy deposited in the first detector material in a first energy range; recording a spectrum of the total energy deposited in the first detector material; determining a first energy deposited in a first energy range; determining a second energy deposited in a second energy range; and comparing the first deposited energy with the second deposited energy.
