Liver needle biopsy B ultrasonic image processing method and system based on mathematical model

The invention relates to the technical field of image processing, in particular to a mathematical model-based liver needle biopsy type-B ultrasonic image processing method and system.The method comprises the following steps of: when a liver type-B ultrasonic image is processed through a mathematical model, firstly, recognizing an image of a final target area through an image comparison method; then the final target area is input into the mathematical model to be recognized, the time for the mathematical model to process the B-mode ultrasound image can be greatly shortened, and the processing precision can be improved; besides, for the condition that different B-mode ultrasound images have different resolutions, when the image of the final target area is marked, the number of pixel points of the image of the target area is judged, and the initial target area is adjusted according to the number of the pixel points; and more information is expected to be included, so that the image processing accuracy of the mat
