Abstract: The present invention relates to an X-ray imaging system (10), comprising a radiograph X-ray attenuation image acquisition unit (20), at least one sensor (30), and a processing unit (40). The radiograph X-ray attenuation image acquisition unit is configured to acquire a radiograph image of a patient. The radiograph X-ray attenuation image acquisition unit is configured to provide the radiograph image to the processing unit. The at least one sensor is configured to acquire sensor data of the patient. The at least one sensor is configured to provide the sensor data to the processing unit. The processing unit is configured to determine a magnitude and direction of movement of the patient during a time of acquisition of the radiograph image, the determination comprising utilization of the sensor data. The processing unit is configured to post-process the radiograph image comprising utilization of the determined magnitude and direction of movement of the patient during the time of acquisition of the radiograph image.

Abstract: The present invention relates to a device (34) and a method (70) for determining a status of an X-ray tube (10) of an X-ray system (36). Due to ageing and/or wear of the X-ray tube, the spectrum of the X-ray radiation (30) provided by the X-ray tube may change over the operation time of the X-ray tube. The present invention therefore suggests evaluating spectrally different values detected with an X-ray detector arrangement (32) of the X-ray system. A reference data set representing a reference condition of the X-ray tube by a plurality of spectrally different reference-values (44) and a working data set representing an aged condition of the X-ray tube by a plurality of spectrally different working-values (46) of detected X-ray radiation are used to determine an equivalent filtration function for an filtration material influencing a source X-ray radiation (26) emitted by an anode (16) of the X-ray tube. Accordingly, the filtration function provides the information about the material being used for the filtration and/or its length, which may provide the basis to determine the condition and thus the status of the X-ray tube.
