An automatic vertebral body recognition method based on coronal ultrasound images of spine

Abstract

An automatic vertebral recognition method based on ultrasonic coronal plane image of a spine comprises the following steps: 1) segmenting a vertebral body one by one in target spine segment ultrasonicimage by using the ultrasonic image segmentation technology; 2) performing identifying according to the characteristic anatomical structure, the characteristic vertebral body and the characteristic structure of the vertebral body, judging and identifying the characteristic vertebral body according to the characteristic anatomical structure, and calculating other vertebral body from the characteristic vertebral body; 3) performing verifying and calibrating by characteristic anatomy and vertebral body characteristics. The invention gives consideration to the accurate and efficient identification of ultrasonic bone image features, By using the original ultrasonic image segmentation method of spine, the characteristic anatomical structure of different vertebral segments of the spine is recognized, and the characteristic vertebral body is judged by the characteristic vertebral body. Then the other vertebral bodies are deduced from the count of the characteristic vertebral body according tothe long axis direction of the spine, until the target operative segment. Finally, the characteristic anatomical structure and the characteristic vertebral body are deduced by the bidirectional count, and the identification verification and calibration are completed.

Description

technical field [0001] The invention belongs to the field of medical image processing, and relates to an automatic vertebral body recognition method based on a spinal ultrasound coronal image. Background technique [0002] With the vigorous development of computer navigation systems, intraoperative navigation of the spinal cord has attracted more and more attention. Through precise positioning, it is expected to greatly solve the positioning problems in spinal cord-related operations, especially in minimally invasive operations, and reduce the technical threshold to promote this advanced technology. promotion and popularization. At the same time, in order to solve the radiation damage in the current mainstream navigation technology, the navigation method based on ultrasound images has gradually become a research hotspot in the industry. Although ultrasound has many advantages such as non-invasive, non-radiation, real-time and economical, it has a large attenuation and diffr...
