This patent describes an x-ray apparatus. It comprises: an x-ray tube which includes a rotating anode; diaphragm means for forming an x-ray radiation beam from x-rays produced at a focal spot on the anode; x-ray recording means disposed in the beam; means which effect a relative movement of the recording means with respect to the beam during an x-ray exposure of the recording means; and synchronizing means which adjust the rate of rotation of the anode and/or the relative speed of the beam with respect to the recording means as a function of an intensity profile of the beam at the recording means to compensate the exposure of the recording means for fluctuations in the intensity of the beam which are caused by periodic movement of the focal spot.
