Method and system for automatically intercepting ultrasonic image and evaluating quality of ultrasonic image

The invention provides a method and a system for automatically intercepting an ultrasonic image and evaluating the quality of the ultrasonic image. The method comprises the following steps: monitoring movement information of an ultrasonic probe in a working mode; when the movement information represents that the ultrasonic probe is in a static state and the static duration is greater than a duration threshold value, intercepting at least one currently acquired to-be-processed ultrasonic image; identifying an image category of the to-be-processed ultrasonic image, wherein the image category is used for representing that the to-be-processed ultrasonic image is an image of any human tissue; a target model is determined from the image quality evaluation models corresponding to the image categories, and the target model is an image quality evaluation model corresponding to the image category of the to-be-processed ultrasonic image; and inputting the to-be-processed ultrasonic image into the target model for image
