Abstract

A computer tomograph detector for the detection of electromagnetic radiation transmitted by an object, which detector includes at least one detector row which consists of a plurality of detector elements, each detector element including a scintillator for converting radiation of a first energy level into radiation of a second energy level, as well as a photosensor for converting the radiation into an electrical current, each photosensor being associated with an amplifier element, is extended in such a manner that it can include a plurality of detector rows while the electronic noise is nevertheless reduced and at the same time a higher DQE is obtained; this is achieved by arranging a plurality of photosensors and the associated amplifier elements on the same substrate in integrated semiconductor technique.
