Abstract: The invention relates to a radiation detector (100) and an associated method for the detection of (e.g. X or ?-) 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).

Abstract: The invention relates to a radiation detector (100) comprising a converter element (102) for converting incident high-energy radiation (X) into charge signals. A cathode (101) and an array(104) of anodes (103) are disposed on different sides of the converter element(102) for generating an electrical field (E0, Ed) within it. The strength of said electrical field(E0, Ed) is increased in a first region(Rd) near the anode array(104) with respect to a second region(R0) remote from it. Such an increase may be achieved by doping the first region(Rd) with an electron acceptor. The increased field strength in the first region(Rd) favorably affects the sharpness of charge pulses generated by incident radiation.

Abstract: 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.

Abstract: 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).

Abstract: Scattered radiation has non-intuitive properties. A signalling system (28) is presented which provides a perceptible signal (34) being indicative of a predicted or measured spatial distribution of scattered radiation. An embodiment provides for easy assessment of the individual risk of scattered radiation exposure for personnel working in an environment exposed to scattered radiation. A method for predicting a distribution of scattered radiation takes into account at least one object related parameter (18) and at least one radiation related parameter (22) and, in response hereto, predicts a distribution of scattered radiation.
