Abstract

The invention discloses a filament correction method, a device and an electronic device, wherein, the method comprises the steps of obtaining a current filament current; Obtaining the current tube current by using the current filament current; Extracting the current correction step size and the last tube current; Adjusting the next correction step length according to the current tube current, thecurrent correction step length and the last tube current; Calculating a next filament current based on the current filament current and the next correction step. The next calibration step is adjustedaccording to the change of the current. When the change of the current is larger and larger, the calibration step is automatically reduced, and the precision of the current is improved. In addition, the accuracy of the tube current can be ensured with the least number of exposure times by the filament correction method with variable step size, and the service life of the ray tube can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of ray generating devices, in particular to a filament calibration method, device and electronic equipment. Background technique [0002] A radiation generating device is a commonly used medical device, which is used to form a photographic image by irradiating radiation to the party to be detected and receiving the radiation that penetrates the party to be detected. In a radiation generating device, radiation is generated and emitted from a radiation tube. [0003] Specifically, the ray tube is a high-vacuum cathode ray diode, which has an anode and a cathode, and a filament is arranged on the cathode. During the operation of the ray tube, by applying current to the cathode filament, the filament is heated and free electrons are generated, and then a high voltage is applied to the cathode and anode. Due to the sharp increase in the potential difference between the cathode and the anode, driven by a...
