Abstract:
An apparatus for forming an image by means of radiation, including a radiation detector unit for output of the image, the radiation detector unit comprising:image detector elements which are arranged in a matrix of rows and columns and each of which includes an image sensor element, being sensitive to the imaging radiation, and a controllable switching element connected thereto, each column being subdivided into a plurality of groups of image detector elements,a plurality of column-read conductors, wherein a column-read conductor is provided in each column for each group of image detectors, and wherein each column-read conductor is connectable, via the associated controllable switching elements, to image detector elements of one group of image detector elements associated with the relevant column, and transfers the output of connectable detector elements to read amplifiers for output,read drivers for driving the switching elements so as to read an electric variable from the image detector elements by connecting them to the column-read conductors, androw-control conductors, wherein at least one row-control conductor is provided for each read driver and connects the output of the connected read driver to the respective control electrodes of the controllable switching elements associated with at least two rows,wherein each read driver is connected to at least two rows of image detector elements which are not associated with the same column-read conductor, the number of rows thus connected to one read driver being at the most equal to the number of groups of image detector elements in one column.
