Abstract
The present invention relates to a photon detector, a detector device and an imaging apparatus for detection of radiation, in particular gamma radiation. The photon detector comprises a direct conversion detector () configured to detect gamma radiation and generate direct conversion signals responsive to impingement of photons, a single photon avalanche diode. SPAD, detector array () comprising a plurality of SPAD detectors () configured to detect Cherenkov radiation generated in the direct conversion detector in response to impingement of photons and generate SPAD detection signals, and an electrode array () comprising aurality of electrodes arranged on top of the direct conversion detector and between the direct conversion detector and the SPAD detector array and configured to read out the direct conversion signals. The SPAD detector array substantially covers a surface on one side of the direct conversion detector.
