Abstract
The invention relates to a method and a device for adapting a radiation dose of an X-ray source ( ). The X-ray source ( ) irradiates an object to be examined, for example, a patient ( ), so as to form an X-ray image ( ) on an X-ray detector ( ). The X-ray image ( ) is subdivided into image regions (A-I) and each time the brightest image region is successively separated from the remaining image regions in an iterative method if its mean grey value forms an indication of the presence of direct radiation ( ) in the relevant image region. The image regions still remaining at the end of the iteration operation correspond to an image region of interest which can be taken into account by a control unit ( ) so as to calculate the optimum radiation dose.
