Method and device for plane image processing of levator ani muscle axis

Abstract

The invention discloses an anal levator shaft plane image processing method and a device thereof. The method is characterized by acquiring three-dimensional volume data of a basin floor; according to the three-dimensional volume data, carrying out image detection on a basin-floor-center sagittal image and identifying a pubic symphysis lower margin and a rectum and anal canal connection portion; acquiring a connection line of the pubic symphysis lower margin and the rectum and anal canal connection portion, adjusting the connection line and making the connection line be in a horizontal direction; and according to the connection line of the horizontal direction, adjusting a sampling frame and acquiring an anal levator shaft plane image. By using the anal levator shaft plane image processing method and the device thereof, the pubic symphysis and the rectum and anal canal connection portion can be automatically identified so that the sampling frame is rapidly and accurately adjusted and an anal levator area image is acquired; and accuracy and efficiency of image processing are increased.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic imaging, in particular to a method and device for processing a plane image of a levator ani muscle axis. Background technique [0002] The levator ani muscle is composed of visceral pubone muscle, puborectalis muscle, and iliococcygeus muscle, and is the most important pelvic floor muscle supporting the pelvic organs. The levator ani muscle on both sides and the lower edge of the pubic symphysis jointly form the levator ani muscle hiatus, through which the urethra, vagina, and rectum pass. If the levator ani muscle is damaged, it will affect the support of the pelvic organs and cause prolapse. The axial plane of the levator ani muscle can well display the levator ani muscle hiatus and surrounding muscle groups, and evaluate the injury of the levator ani muscle. [0003] In pelvic floor ultrasound imaging, the biggest advantage of 3D / 4D ultrasound is that it can display the axis plane o...

Problems solved by technology

In the actual processing process, due to differences in doctors' techniques, the accuracy of the mid-sagittal plane of the pelvic floor is difficult to guarantee, and due to the lack of understanding of three-dimensional space, it is difficult to locate the position of the posterior inferior edge of the pubic symphysis in the separate volume data to adjust the sampling Box position and size

Therefore, it is difficult for most doctors to efficiently obtain plane images of the levator ani muscle axis in 3D, which reduces the diagnostic accuracy and efficiency
