ABSTRACT:
An apparatus for filtering an x-ray beam emitted by an x-ray source comprises a filter, adjustable from a parked position (P) outside of a path of the x-ray beam into a filtering position (F) in the x-ray beam path. A corresponding first sensor device detects when the filter in the filtering position (F), and a corresponding second sensor device detects when the filter in the parked position (P). Further, sensor signals are communicated by the first and second corresponding sensors to an evaluation device. The evaluation device generates a report if the filter is not in at least one of the parked position (P) and the filtering position (F).
