Zusammenfassung:An ultrasound automated detection and display method of cranial abnormal regions includes: firstly, a skull surface model is constructed; then contour detection is carried out based on a two-dimensional ultrasonic image to obtain a skull contour curve; fitting is carried out on the contour curve and the skull surface model to determine whether the two-dimensional ultrasonic image has symmetry characteristics or not; finally, similarity comparison calculation is carried out on two mutually symmetrical regions by utilizing the symmetry characteristics of the two-dimensional image, so that whether an abnormal region exists and the location of the abnormal region is determined. The method has the advantages that a skull surface model is constructed before detecting a cranial contour curve on a two-dimensional ultrasonic image.
