摘要： The invention relates to a method of reading out the sensor elements of a sensor (1) with a matrix of light-sensitive or X-ray-sensitive sensor elements (S1,2; S1,2 . . . ) which are arranged in rows and columns and generate charges in dependence on the incident quantity of radiation, the switches (3) of the relevant sensor elements being activated via address lines (4, . . . , 8, . . . ) and the charges of the respective activated sensor elements being drained via read-out lines (9, 10, 11, . . . ) so as to be processed further by way of amplifiers (14, . . . , 18, . . . ) and transfer means (19). The invention also relates to a corresponding sensor as well as to an X-ray examination apparatus which includes an X-ray source for emitting an X-ray beam for irradiating an object in order to form an X-ray image, as well as a detector for generating an electrical image signal from said X-ray image. Despite the small incident X-ray doses, adequate amounts of charge, and hence electrical signals, are provided so as to form the image in that ingoing address lines (4, . . . , 8, . . . ) are selectably connected, by way of individually controllable switch elements (27, . . . , 30, . . . ) and by means of a switching operation, to each time the respective next address line and the sensor elements of at least two neighboring lines are activated by means of one ingoing signal, and corresponding outgoing read-out lines (9, . . . , 13, . . . ) are selectably connected, by way of individually controllable switch elements (31, . . . , 34, . . . ) and by means of a switching operation, to the respective next read-out line in such a manner that the charge signals read out from the activated sensor elements of at least two neighboring columns are combined so as to form one output signal.

摘要： The invention relates to a method of generating X-ray images by means of a photoconductor which is provided on a conductive substrate and whose surface potential can be read by means of probes, and also relates to a device suitable for carrying out the method. In order to avoid image artefacts which could be caused by deviating sensitivities of the probes or by frequency-dependent distortions, after the charging of the photoconductor the substrate potential is varied during a test phase. Test data is generated which correspond to the spatial or temporal variation of the potential on the surface of the photoconductor; from this test data there is formed correction data which is stored in order to correct the image data of a subsequent X-ray exposure.

摘要： A photodiode radiation sensor sensitive to luminous or x-ray radiation, has an inherent capacitance which is charged by the radiation. The charge is read out by a switching diode. The diode is placed in its conductive state by an auxiliary voltage and is switched off after the read-out process. The quantity of charge flowing during the read-out process is measured and used to determine the quantity of incident radiation. To measure relatively small quantities of charge, a voltage is coupled in when the auxiliary voltage is switched on to place the switching diode in a more strongly conducting state so that during the read-out process a larger quantity of charge flows away.
