Abstract
An X-ray diagnostic apparatus has at least one beam transmitter which emits an X-ray beam acquired by at least one solid-state detector with image points arranged in the form of a matrix, and at least one correction unit that acquires the image signals, produced by the solid-state detector, of the current bright image exposure of a subject to be examined, and acquires the any afterglow signals which may be present from at least one dark image exposure. The correction unit controls the beam transmitter dependent on the presence of afterglow signals and/or the intensity of the afterglow signals, and, if necessary, corrects the image signals of the current bright image exposure.
