A photoconductor for converting incident X-ray radiation into a charge pattern is on carrier constructed so as to be rotationally symmetrical with respect to an axis of rotation. A driving unit rotates the carrier and photoconductor about the axis of rotation. A charge reading unit which, after exposure to X-rays forming an X-ray picture, converts the charge pattern on the surface of the rotating photoconductor into electric picture values. Reduced picture exposure time (with the time for reading the photoconductor remaining equally low) is achieved in that the converter does not rotate during exposure to the X-rays for taking an X-ray picture.
