摘要： An Y-ray detector apparatus comprises an array of detector pixels arranged into a plurality of sub-arrays. The pixels in each sub-array share a common dose sensing output provided to a dose sensing output conductor which extends to a periphery of the pixel array. The dose sensing output conductor for one sub-array of pixels passes through the area occupied by another sub-array of pixels, which can lead to unwanted cross talk. The invention provides a plurality of additional screening electrodes, with a screening electrode substantially adjacent the dose sensing output conductor for each sub-array of pixels. These screening electrodes reduce cross talk between the dose sensing output and other pixel electrodes. In another arrangement, each pixel further comprises a pixel electrode for each pixel formed at an upper region of the array, and the dose sensing output conductors are formed at a lower regon of the array. An intermediate conductor layer is then provided which overlaps the dose sensing output conductors for other sub-arrays of pixels and which pass through the area occupied by the sub-array of pixels.

摘要： An X-ray detector apparatus has an array of pixels arranged into a plurality of sub-arrays (40). The pixels in each sub-array (40) share a common output (42). The detector is operable in two modes, a dose sensing mode in which a switching arrangement (50) is turned off and charge flow in response to incident radiation is partially coupled through an off-capacitance of the switching arrangement (50) to the output, and a read out mode in which the switching arrangement is turned on to allow charge to flow between the charge storage element and the output (42) for measurement as a detection signal. The switching arrangement (50) is turned on by first and second control signals to enable a single pixel within the sub-array (40) to be selected. Thus, the resolution of normal read out is per-pixel whereas the resolution of dose sensing is per-sub-array.

摘要： The invention relates to an array of sensor elements, wherein the sensor elements are provided to detect electromagnetic radiation such as X-radiation or light, and in doing so to generate a charge signal corresponding to the intensity of the radiation. A sensor element further comprises means enabling the incoming dose of radiation to be determined. In the array, the sensor elements form groups, so that the outputs of all sensor elements of a group are coupled. This on the one hand enables a determination of the dose in these areas, and on the other hand enables images to be formed with a lower resolution in a simple manner, by the combining of output signals from several sensor elements. Furthermore, the sensor elements of one group are preferably arranged “isolated” in such a way that they are surrounded by sensor elements of other groups. Such an array can be used, for example, in an X-ray diagnostic facility or in an optical image recording system.

摘要： The invention relates to a detector and a method for the production of consecutive X-ray images. This involves the generation in the detector by X-radiation during an exposure interval (Texp) of a current flow (I(t)) which is integrated (Qdk*, Qsig*, Qac*) in a memory capacity and read out in a subsequent readout phase (Trd). In order to minimize the influence of slowly decaying residual currents (Iac), the current (I(t)) is integrated only during the exposure interval (Texp). By this means, disturbing artifacts due to residual signals from earlier photographs are minimized.

摘要： The invention relates to a detector element (1) for gamma radiation, which is particularly suitable for use in a PEF apparatus. The detector element (1) consists of two or more different conversion units (11, 12), which react to the absorption of a gamma quantum (y) with light emissions (λ1, λ2) of different spectral composition. A photodetector arrangement (30) may therefore discriminate between the sites of origin of the light emissions by means of their spectral characteristics.
