An X-ray examination apparatus for examination of composite objects, such as, for example, peripheral examination of patients, comprises, in order to avoid over-radiation of the detection system by radiation passing along the object, a filter that can be adapted to the interstices. Such a filter consists, for example, of a body of radiation-absorbing material having in two directions a varying radiation absorption, for example in the form of a double wedge. |
