Description

【Technical field】 [0001] The present application relates to medical imaging equipment, in particular to an X-ray tube filament control system and method for medical imaging equipment. 【Background technique】 [0002] Computed Tomography (CT) equipment has a wide range of applications in the field of medical imaging. In the process of CT imaging, X-ray tube can be used for wire release. Because different tissues have different densities and absorb X-rays differently, CT equipment can complete images of human tissues. In different CT scanning scenarios, the working parameters of a single X-ray tube filament (eg, filament preheating current, preheating time, etc.) may lead to high or low filament temperature, which cannot meet the imaging requirements of different CT scans. Accurate and efficient calibration of the X-ray tube filament is still a difficult point at this stage. Therefore, a system and method are needed to solve the above problems. 【Content of invention】 [0...
