Title:
SYSTEM AND METHOD FOR CONTROLLING FILAMENT OF X-RAY TUBE
Document Type and Number:
WIPO Patent Application WO/2017/143974
Kind Code:
A1
Abstract:
A method for correcting filament current data of an X-ray tube, comprising acquiring a first to-be-corrected tube current value and a to-be-corrected filament current value corresponding to a first correction point; executing a pay-off operation according to the first to-be-corrected tube current value and to-be-corrected filament current value; determining an actual tube current value in the pay-off operation; determining the difference between the actual tube current value and the first to-be-corrected tube current value; and correcting the first correction point according to the difference. Also disclosed are a corresponding correction system, a method and system for preheating filament of X-ray tube, as well as a computer-readable medium including instructions by which the correction method and the preheating method can be executed.
