Abstract

The embodiment of the invention provides a filament current adaptive correction method and device for X-ray equipment, and the method comprises the following steps: determining a target tube current of the X-ray equipment, and determining a preset filament current corresponding to the target tube current through a pre-established parameter comparison table, the corresponding relation between the tube current and the filament current is recorded in the parameter comparison table; taking the determined preset filament current as an input initial value of closed-loop control, taking detection results of the actual filament current and the actual tube current of the X-ray equipment as feedback information of the closed-loop control, adjusting the filament current to enable the tube current of the X-ray equipment to be stabilized at the target tube current, and recording the actual filament current fed back each time; calculating a target filament current corresponding to the corrected target tube current by using the actual filament current; and updating the preset filament current corresponding to the target tube current in the parameter comparison table by using the calculated target filament current. Through the method, adaptive correction of the filament current of the X-ray equipment is realized.

Description

technical field [0001] The invention relates to the technical field of correction, in particular to a method and device for self-adaptive correction of filament current of X-ray equipment. Background technique [0002] As one of the basic structures of X-ray equipment, the X-ray tube is also the core component for generating X-rays. The X-ray tube is a vacuum tube, which contains a cathode and an anode inside, and a filament is connected to the cathode. When the X-ray equipment is working, the current loaded on the cathode filament of the X-ray tube is the filament current, and the current between the cathode and anode of the X-ray tube is The voltage is called the tube voltage, and the current formed by the electrons excited by the heating of the X-ray tube filament under the action of the high-voltage electric field of the cathode and anode is called the tube current. The tube current of the X-ray tube determines the amount of X-ray radiation, which has a decisive impact ...
