Abstract
The invention relates to a radiation detector that is particularly suited for energy resolved single X-ray photon detection in a CT scanner. In a preferred embodiment, the detector has an array of scintillator elements in which incident X-ray photons are converted into bursts of optical photons. Pixels associated to the scintillator elements determine the numbers of optical photons they receive within predetermined acquisition intervals. These numbers can then be digitally processed to detect single X-ray photons and to determine their energy. The pixels may particularly be realized by avalanche photodiodes with associated digital electronic circuits for data processing.
