Abstract
The invention relates to an arrangement with light-sensitive or X-ray-sensitive sensors which are arranged in rows and columns of a matrix and generate charges in dependence on the amount of incident radiation, each sensor including a photosensor element with an intrinsic storage capacitor and/or a storage capacitor connected parallel to its terminals, and also a respective transistor; it also includes at least one switching line for each row of sensors via which the transistors can be activated so that the charges of the relevant activated sensors S can be read out simultaneously via read-out linesin order to ensure that, in conformity with the relevant mode of operation of the arrangement, the switching noise caused by the reading out of the sensors is reduced and/or a higher image repeat rate or more stable operating conditions for the photosensor element, also in the case of large signals, as well as an increase of the dynamic range of the photosensor element become possible in that each sensor S includes a further transistorwhich is connected directly to the photosensor elementand can be activated via at least one control line, both transistorsof each sensor S being connected in series and an electrode of a further capacitorbeing connected to the junction of the two transistors
