A digital radiographic unit is disclosed which includes a counting flat image detector for taking radiographs from an x-radiation with the aid of pixel readout units, adjacent in a matrix, for measuring and counting charge pulses generated by x-ray quanta of the x-radiation. A coincidence, occurring within a specific time interval, of charge pulses of a pixel readout unit and of charge pulses of at least one bordering pixel readout unit, is detected and the corresponding charge pulses are summed to form a total charge pulse as basic variables for a further evaluation.
