Claim Text:
1. A boosting/blanking method comprising the steps of: a) measuring temporal variation of a tube current of an X-ray tube during boost; b) storing the temporal variation in a first memory; c) applying a boosting/blanking current to a filament of a cathode of the X-ray tube for a short time interval; d.1) determining, based on the stored temporal variation, the tube current after the short time interval; d.2) determining, based on the stored temporal variation, whether the tube current after the short term interval is less than a target value; and d.3) if the tube current after the short term interval is determined to be less than said target value, returning to step c); wherein if, instead, the tube current after the short term interval is determined not to be less than said target value, returning to step c) is not performed.
