Abstract: The present invention relates to a rotary anode X-ray source. In addition to a primary cathode of a rotary anode X-ray tube, an auxiliary cathode is provided in the rotary anode X-ray tube. Electrons from the auxiliary cathode are focused into an area on the anode, from which X-rays cannot enter the used X-ray beam generated by the primary cathode. An emission current controlling device is used to control the electron emission of the auxiliary cathode. Thus, the voltage down-ramp for dual energy scanning is kept constant even though the primary X-ray output changes for the sake of dose modulation or during a transient of the primary electron current.

Abstract: The rotatable anode of a rotating anode X-ray source has demanding requirements placed upon it. For example, it may rotate at a frequency as high as 200 Hz. X-ray emission is stimulated by applying a large voltage to the cathode, causing electrons to collide with the focal track. The focal spot generated at the electron impact position may have a peak temperature between 2000° C. and 3000° C. The constant rotation of the rotating anode protects the focal track to some extent, however the average temperature of the focal track immediately following a CT acquisition protocol may still be around 1500° C. Therefore, demanding requirements are placed upon the design of the rotating anode. The present application proposes a multi-layer coating for the target region of a rotating X-ray anode which improves mechanical resilience and thermal resilience, whilst reducing the amount of expensive refractory metals required.

Abstract: A first set of records and a second set of records different from the first set of records are obtained. A score that indicates indicating confidence that the first set of records and the second set of records correspond to a same individual is computed. As a result of the score reaching a value relative to a threshold, a device of an individual associated with the second set of records is caused to prompt the individual to confirm control of a first asset identified by first data within the first set of records. A message to a destination associated with the first asset is provided. As a result of a response to the message indicating that the individual is the same individual, an association between the second set of records and the first asset is stored and the device is caused to display details about the first and second sets of records.
