Method and device for load dependent resizing of a focal spot of an X-ray generating device

摘要

In an X-ray generating device (2) a temperature of a focal spot (21) may be determined. Furthermore a load condition is determined, which may also take into account a planned operation procedure of the X-ray generating device (2). The focal spot of the X-ray generating device is then automatically resizable based at least in part on the load condition.

主权项

1. A method for load dependent resizing of a focal spot of an x-ray generating device, the method comprising:
determining that, due to overheating, catastrophic failure of said device is imminent; and, dynamically responsive to said determining that said failure is imminent, automatically enlarging said focal spot.
