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).

An apparatus for filtering an x-ray beam emitted by an x-ray source, the apparatus comprising:
- 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;
- and
- a first sensor device for detecting the filter in the filtering position (F), and a second sensor device for detecting the filter in the parked position (P),
- wherein the first and second sensor devices are operable to communicate sensor signals to an evaluation device, the evaluation device operable to generates a report if the filter is not in at least one of the parked position (P) and the filtering position (F).
An imaging x-ray system having an x-ray source and an apparatus for filtering an x-ray beam emitted by the x-ray source, the system comprising:
- a plurality of filters, each independently 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, and each of the plurality of filters having corresponding first and second sensor devices, wherein each corresponding first sensor device detects whether the respective one of the plurality of filters is in the filtering position (F), and each corresponding second sensor device detects whether the respective one of the plurality of filters is in the parked position (P);
- and
- an evaluation device, wherein the first and second sensor devices are operable to communicate sensor signals to the evaluation device, the evaluation device operable to generates a report for each one of the plurality of filters that is not in at least one of the parked position (P) and the filtering position (F).
