A method for measuring the cobb angle of spine x-ray images

Abstract

The invention discloses a method for measuring the cobb angle of X-ray images of the spine, comprising: detecting the key point of the vertebral body; inputting a Dicom image or a general image, performing preprocessing to obtain an image of the vertebral body area, and inputting the image of the vertebral body area into the key point of the vertebral body The point detection model identifies the key points of the vertebral body; calculates and generates the waveform diagram of the included angle of the vertebral body; according to the key points, calculates the angle between the upper and lower end line segments of each vertebral body and the horizontal line to obtain multiple angles, and then in a certain order Draw the waveform diagram of the included angle of the vertebral body; solve the Cobb angle; analyze and calculate the target Cobb angle through the waveform diagram of the included angle of the vertebral body obtained in step S2. The present invention constructs an image deep learning recognition algorithm combined with an artificial Cobb angle intelligent measurement algorithm to intelligently measure the Cobb angles of the upper thoracic curve, thoracic curve, and thoracolumbar / lumbar curve, which meets the clinical Cobb angle test requirements.

Description

technical field [0001] The invention belongs to the technical field of spinal deformity measurement, and in particular relates to a method for measuring the Cobb angle of a spinal X-ray image. Background technique [0002] Spinal deformities are common spinal disorders, among which scoliosis is the most common. According to different causes, it can be divided into: idiopathic scoliosis, congenital scoliosis, neuromuscular scoliosis, degenerative scoliosis, etc., of which idiopathic scoliosis accounts for about 80%. The cause of idiopathic scoliosis (Idiopathic scoliosis IS) is unknown, and the International Scoliosis Association (Scoliosis Research Society) stipulates: the lateral curvature of the coronal plane of the spine exceeds 10 degrees as measured by the Cobb angle, which is called scoliosis. It is often associated with abnormalities in the sagittal plane of the spine and rotational deformities in the axial plane of the vertebral body. According to the age of onset,...

Problems solved by technology

Studies have shown that if the Cobb angle of the scoliosis image is between 25 degrees and 45 degrees or higher, surgical treatment is recommended, and if it is lower than 25 degrees, conservative treatment is recommended, so large errors are likely to affect the doctor's diagnosis; Selecting the upper and lower end vertebrae of scoliosis for scoliosis Cobb angle measurement may cause an error of up to 11.8 degrees, which greatly affects the diagnosis and treatment of scoliosis patients; scoliosis Cobb angle measurement is cumbersome and time-consuming. Increased possibility of measurement error
