A method for detecting spinal deformation by three-dimensional ultrasound imaging

Abstract

The present invention relates to a method of three-dimensional ultrasound imaging for the assessment of scoliosis. A method for detecting spine deformation by three-dimensional ultrasound imaging, comprising the following steps: S1, acquiring a three-dimensional image of the spine with a three-dimensional ultrasound imaging system; S2, acquiring information on the axial rotation of the spine through the three-dimensional image of the spine; S3, using the information on the axial rotation of the spine to The three-dimensional image is adjusted accordingly; S4, the adjusted three-dimensional image of the spine is projected on the coronal plane and / or sagittal plane to obtain the projection map of the coronal plane and / or sagittal plane; S5, through the coronal plane or sagittal plane The projection map calculates spine deformation data. The present invention obtains a three-dimensional image through a three-dimensional ultrasonic imaging system, obtains the rotation of the spine body in the data of the three-dimensional image by analyzing the rotation information and image information of each two-dimensional ultrasonic image, and estimates the rotation center of each two-dimensional image through statistical information of the spine. This method can more accurately measure the deformation angle of the spine in each plane.

Description

technical field [0001] The present invention relates to a method of three-dimensional ultrasound imaging for the assessment of scoliosis. Background technique [0002] In recent years, three-dimensional ultrasound imaging technology has been widely used in the measurement of human spine deformation, such as the evaluation of scoliosis, and achieved quite good results. But because ultrasound can only get images at the back of the spine (that is, from the back), the images obtained are mainly about spinous processes and spinous processes or other spinal bones at the back. Due to the anatomical structure of the spine, when the spine When the main body of the bone rotates, the structure behind the spine bone acquired by the ultrasound image will have a relatively large rotation distance, which greatly affects the measurement of the degree of scoliosis. influences. This is also a shortcoming between the current measurement of spinal curvature by ultrasound imaging compared to X...

But because ultrasound can only get images at the back of the spine (that is, from the back), the images obtained are mainly about spinous processes and spinous processes or other spinal bones at the back. Due to the anatomical structure of the spine, when the spine When the main body of the bone rotates, the structure behind the spine bone acquired by the ultrasound image will have a relatively large rotation distance, which greatly affects the measurement of the degree of scoliosis. influences

This is also a deficiency between the measurement of spinal curvature by ultrasound imaging compared with X-ray image detection
