Claim One:
1. An X-ray examination apparatus which includes an X-ray source, an X-ray detector, and an exposure control system for controlling the X-ray source and the X-ray detector, which exposure control system is arranged to control the X-ray source so as to carry out a test exposure with a low X-ray dose while producing a control signal by means of the X-ray detector, and to control the X-ray source on the basis of the control signal in order to carry out an X-ray exposure with a high X-ray dose and to acquire an X-ray image by means of the X-ray detector during this exposure, characterized in that the exposure control system is arranged to adjust the X-ray detector to a coarse spatial resolution during the execution of the test exposure, and to adjust the X-ray detector to a fine spatial resolution during the execution of the X-ray exposure.
