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： A radiation detector assembly (20) includes a detector array module (40) configured to convert radiation particles to electrical detection pulses, and an application specific integrated circuit (ASIC) (42) operatively connected with the detector array. The ASIC includes signal processing circuitry (60) configured to digitize an electrical detection pulse received from the detector array, and test circuitry (80) configured to inject a test electrical pulse into the signal processing circuitry. The test circuitry includes a current meter (84) configured to measure the test electrical pulse injected into the signal processing circuitry, and a charge pulse generator (82) configured to generate a test electrical pulse that is injected into the signal processing circuitry. The radiation detector assembly (20) is assembled by operatively connecting the ASIC (42) with the detector array module (40), and the signal processing circuitry (60) of the ASIC of the assembled radiation detector assembly is tested without the use of radiation.

摘要： The present invention relates to an apparatus (10) for counting X-ray photons (12, 14). The apparatus (10) comprises a sensor (16) adapted to convert a photon (12, 14) into a charge pulse, a processing element (18) adapted to convert the charge pulse (51) into an electrical pulse (53) and a first discriminator (20) adapted to compare the electrical pulse (53) against a first threshold (TH1) and to output an event (55) if the first threshold (TH1) is exceeded. A first counter (22) counts these events (55), unless counting is inhibited by a first gating element (24). The first gating element (24) is activated when the first discriminator (20) outputs the event (55), and it is deactivated, when the processing of a photon (12, 14) is found to be complete or about to be completed by a measurement or by the knowledge about the time that it takes to process a photon (12, 14) in the processing element (18). By activating and deactivating the first counter (22) pile-up events, i.e. pile-up of multiple electrical pulses (53), can be addressed. The invention also relates to a corresponding imaging device and a corresponding method.

摘要： The invention relates to a radiation detector (200), particularly an X-ray detector, which comprises at least one sensitive layer (212) for the conversion of incident photons (X) into electrical signals. A two-dimensional array of electrodes (213) is located on the front side of the sensitive layer (212), while its back side carries a counter- electrode (211). The size of the electrodes (213) may vary in radiation direction (y) for adapting the counting workload of the electrodes. Moreover, the position of the electrodes (213) with respect to the radiation direction (y) provides information about the energy of the detected photons (X).

摘要： The invention relates to a radiation detector (100) comprising a converter element (113) with an array (120) of first electrodes (121) for sampling electrical signals generated by incident radiation (X). With a connection circuit (130), at least two first electrodes (121) can selectively be coupled to a common readout unit (141) according to a given connection pattern (CP1). The effective pixel size along the path of incident radiation (X) can thus be adapted to the distribution of electrical signals, which is usually determined by the spectral composition of the incident radiation.

摘要： The invention relates to converter element (100) for a radiation detector, particularly for a Spectral CT scanner. The converter element (100) comprises at least two conversion cells (131) that are at least partially separated from each other by intermediate separation walls (135) which affect the spreading of electrical signals generated by incident radiation (X). The conversion cells (131) may particularly consist of a crystal of CdTe and/or CdZnTe. Said crystal is preferably grown by e.g. vapor deposition between preformed separation walls.
