Three-dimensional visualization method based on spine three-dimensional ultrasonic volume data

Abstract

The invention discloses a three-dimensional visualization method based on spine three-dimensional ultrasonic volume data. The method comprises the steps: generating a coronal section projection drawing and a sagittal section projection drawing for different depths of a skin surface based on the spine three-dimensional ultrasonic volume data; determining spine spinous processes and tip positions thereof on the sagittal section projection drawing, and segmenting and positioning boundary positions of the spine spinous processes and spine vertebral bodies in the coronal section projection drawingwith the corresponding depth; determining the spatial position and posture of each spine under the three-dimensional ultrasonic data coordinate system based on the tip of the spine spinous process andthe boundary position of the spine spinous process and the spine body; based on a three-dimensional display model of a standard spine, matching points of three feature points of the left end point, determining the right end point and the tip end of a spine spinous process in the three-dimensional display model for each spine, wherein the three feature points are located at the boundary position of the spine spinous process and a spine body; and according to the spatial position of each spine in the three-dimensional ultrasonic data coordinate system, matching the corresponding spatial position of the standard three-dimensional display model in the three-dimensional ultrasonic data coordinate system to generate an overall three-dimensional spine model.

Description

technical field [0001] The present invention relates to the medical field, and more specifically relates to a three-dimensional visualization method based on three-dimensional ultrasound volume data of the spine, which can be used in medical imaging equipment. Background technique [0002] Scoliosis is an abnormal musculoskeletal state caused by three-dimensional distortion of the spine. It is manifested by abnormal bending or rotation of the spine in three-dimensional space, making the intervertebral disc bear abnormal weight and the spine cannot move normally and freely. . Adolescence is a period of high incidence of scoliosis. For adolescents who are in the growth and development period, maintaining an improper trunk posture for a long time can easily deform the spine. If it is not detected early and treated in time, the spine will produce irreversible distortion. Among them, kyphosis is a common visible spinal deformity related to scoliosis. In kyphosis, the angle of cu...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to propose a spine data visualization method based on the vertebral body model in view of the limitation that the traditional three-dimensional ultrasound data of the spine cannot provide complete vertebral body structure information
