摘要： The invention relates to a radiation detector (100) and an associated method for the detection of (e.g. X or γ-) radiation. The detector (100) comprises a converter element (110) in which incident photons (X) are converted into electrical signals, and an array of anodes (130) for generating an electrical field (E) in the converter element (110). At least two anodes are associated with two steering electrodes (140) to which different potentials can be applied by a control unit (150). Preferably, each single anode or small group of anodes is surrounded by one steering electrode. The potentials of the steering electrodes (140) may be set as a function of the potentials that are induced in these electrodes when an operating voltage is applied between the anodes and a cathode (120). Moreover, a grid electrode (160) may be provided that at least partially encircles anodes (130) and their steering electrodes (140).

摘要： In radiation-sensitive detector devices, such as direct conversion detectors, charges are drifting within an externally applied electric field towards collecting electrodes (4), which are segmented (e.g. representing a pixel array). At the gaps between segments, electrical field lines can leave the detector, and charges drifting along those field lines can be trapped within the gap. This can be avoided by external electrodes (8) which push electric field lines back into the direct conversion material.
