Abstract: Disclosed are a convex-linear bi-plane probe and its application method in prostate volume calculation. The present invention adopts the following technical solution: comprising a probe housing and a probe assembly contained in the probe housing, the probe assembly comprising a linear probe and a convex probe contained at the end of the linear probe, with the linear element inside the linear probe and the convex element inside the convex probe connected as one piece. The benefits of the present invention are that: by setting a convex probe at the end of the linear probe, and by connecting the linear element and the convex element as one, the volume of the probe can be significantly reduced. Furthermore, the use of convex-linear biplane probe and its integrated design collect two orthogonal ultrasound images of the prostate, which improves the accuracy of prostate volume calculation.

Abstract: The present disclosure relates to the field of ultrasonic detection, in particular to a craniocerebral ultrasonic standard plane imaging and automatic detection and display method for abnormal regions. The following technical solution is adopted: contour detection is performed on the scanned ultrasound images the skull to construct a skull surface model, and the standard planes in ultrasound images are identified and extracted according to the skull surface model. The symmetry of the standard planes in ultrasound images is used to compare the similarity, so as to obtain the abnormal regions for segmentation and display. The advantages of the present disclosure are as follows: the skull surface model is constructed by detecting the cranial edge, and the coordinate system is established based on this model, thereby the standard planes in ultrasound images can be quickly identified from the scanned ultrasound images.

Abstract: 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.
