X-ray unit with adjusted recording speed

The invention relates to a system and a method for receiving an X-ray image. The invention is based on a system for the acquisition (A) of an X-ray image (2) comprising a receiving unit (AE), adapted to receive (A) an X-ray image (2) at least one body areas of a patient (3). The invention is based on the idea that the system further comprises a control unit (StE), which (St) of the speed of at least one relative movement between the patient (3) and the receiving unit (AE) as a function of the X-ray absorbing properties (13) at least for controlling a body region of the patient (3) is designed. This has the advantage that a control (St) of the velocity allows the regulation of the dose for a given body area of ​​the patient (3) independent of the intensity of X-ray radiation (17).
