IMAGE EXTRACTION METHOD AND DEVICE IN ULTRASONIC SCANNING, AND ULTRASONIC IMAGING SYSTEM

摘要

Disclosed in the present invention is an image extraction method in ultrasonic scanning. The method comprises the steps of: obtaining a time point for triggering image position selection in continuously collected ultrasonic images; obtaining, according to the time point, multiple frames of ultrasonic images continuously collected in a preset time period associated with the time point, so as to form a library of ultrasonic images to be selected; determining image section matching degrees of all ultrasonic images in the library of ultrasonic images to be selected, so as to obtain multiple frames of ultrasonic images therein satisfying a section matching degree; recognizing definitions of the multiple frames of ultrasonic images satisfying the section matching degree, so as to obtain one or more frames of ultrasonic images satisfying a definition requirement; and displaying and outputting the one or more frames of ultrasonic images satisfying the definition requirement. Also disclosed in the present invention are a corresponding device and an ultrasonic imaging system. The workload of a user can be reduced, and the work efficiency can be improved.
