Patent ID: 8466412

Claim:
A detection apparatus for photons or ionizing particles, in which a detector system is provided with several detecting units, each including a scintillator connected to a reader surface on an electronic charge reader, the scintillator being arranged to generate cellular charges on the reader surface when capturing the photons or the ionizing particles, and in which, connected to the scintillator opposite the electronic charge reader, a collimator is arranged, which is arranged to capture photons or ionizing particles exhibiting a direction of motion coinciding with a longitudinal axis of the collimator, and to reject photons or ionizing particles exhibiting a direction of motion deviating from the direction of the longitudinal axis of the collimator, and several detector systems being arranged evenly spaced around the centre axis of a detector assembly, wherein the detection apparatus is formed of a stack formed of several detector assemblies, each detector assembly having been rotated around the centre axis of the detector assembly relative to the adjacent detector assembly/assemblies.
