Description

technical field [0001] Embodiments of the present invention relate to the technical field of data subtraction, and in particular to a multi-phase data subtraction method, device, equipment, and storage medium. Background technique [0002] DSA (Digital Subtraction Angiography, Digital Subtraction Angiography) system is an X-ray imaging system that combines conventional angiography technology with computer image processing technology. DSA has the advantages of high contrast resolution, short examination time, less contrast medium consumption, low concentration, significantly reduced X-ray absorption of patients, and film saving. It is of great significance in the clinical diagnosis of vascular diseases. [0003] The existing DSA subtraction methods all subtract the data of a single contrast phase and a single unenhanced phase. The subtraction method is single and has poor flexibility. In addition, in order to obtain a more complete vascular shape, the requirements for the se...
