Method and system for measuring scoliosis Cobb angle by using oscillogram

Abstract

The invention discloses a method and system for measuring a scoliosis Cobb angle by using an oscillogram. The method comprises the following steps that an X-ray image and a plurality of vertebral bodyboundary points of the X-ray image are obtained; vertebral body boundary information corresponding to each vertebral body is generated based on the multiple vertebral body boundary points; vertebralbody end plates corresponding to the vertebral bodies are extracted based on all vertebral body boundary information; and an end plate included angle oscillogram is constructed based on all vertebralbody end plates, a difference value between an included angle maximum value and an included angle minimum value in the end plate included angle oscillogram is calculated, and the scoliosis Cobb angleis generated. The vertebral body end plates corresponding to the vertebral bodies are extracted through the vertebral body boundary points, the included angle of the vertebral body end plates relativeto the horizontal direction is calculated to construct the end plate included angle oscillogram, the scoliosis Cobb angle is generated by calculating the maximum included angle difference value in the end plate included angle oscillogram, manual calibration of the end vertebrae and the lower end vertebrae is effectively avoided, scribing work of end plate parallel lines of the upper end vertebraeand the lower end vertebrae is carried out, the influence of human factors on detection results is avoided, and the detection precision of the scoliosis Cobb angle is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of human posture recognition, in particular to a method and system for measuring the Cobb angle of scoliosis by using a waveform diagram Background technique [0002] Scoliosis is a three-dimensional deformity of the spine that includes sequence abnormalities in the coronal, sagittal, and axial planes. The Cobb angle refers to the intersection angle between the vertical line of the upper edge of the cranial end vertebra and the vertical line of the lower edge of the caudal end vertebra, and is the most critical index for evaluating the severity of scoliosis. The diagnostic standard for scoliosis is that the Cobb angle is greater than 10°, and the surgical indication for scoliosis is that the Cobb angle is greater than 45°. Therefore, accurate measurement of Cobb is particularly important for the diagnosis and treatment of scoliosis. [0003] There are mainly two traditional Cobb angle measurement me...
