Abstract

The present invention relates to a radiation detection device for detecting gamma or x-ray radiation quanta with improved timing accuracy and improved energy resolution. The radiation detection device finds application in the detection of gamma and x-ray radiation and may be used in the field of PET imaging, and in spectral CT. The radiation detection device includes a semiconductor scintillator element and a photodetector. The photodetector is in optical communication with the scintillator element. The scintillator element has two mutually opposing faces; a cathode is in electrical communication with one of the two faces and an anode is in electrical communication with the other of the two faces.

Description

technical field [0001] The invention relates to a device for the detection of gamma-ray or X-ray radiation quanta. A system and computer readable medium for use in accordance with the device are also disclosed. The invention finds particular application in the detection of radiation quanta in the field of nuclear imaging and X-ray imaging. More specifically, the invention applies to PET imaging systems and spectral CT imaging systems. Background technique [0002] Conventionally, detectors for ionizing radiation such as gamma-ray radiation quanta and X-ray radiation quanta used in eg PET imaging systems or X-ray imaging systems include scintillator elements and photodetectors. The scintillator element receives radiation quanta and converts each radiation quanta into a pulse of infrared, visible or ultraviolet light that is detected by a photodetector. The electrical pulses obtained from the photodetector are then analyzed to determine the properties of the radiation quant...
