Embodiment Construction

[0029] The method for measuring the curvature angle of the spine of the present invention, by performing correlation processing on the spine image obtained by three-dimensional ultrasound imaging, obtains the curve points on the spine, thus forming a spine curve, and then calculating the spine curvature angle according to the inflection point on the spine curve, It makes it easy and feasible to use three-dimensional ultrasound images to measure the curvature angle of the spine. At the same time, the curve points are obtained manually, or by a computer-aided method, or the combination of the two methods meets the needs of different users who use the three-dimensional imaging system, thereby improving the accuracy of measuring the curvature angle of the spine.

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and emb...

Abstract

The invention provides a spinal curvature angle measurement method. The method includes the following steps: S1, acquiring a spinal image through a three-dimensional ultrasonic imaging technique; S2, acquiring curve points located in a spine from the spinal image; S3, generating a final spinal curve according to the curve points; and S4, calculating out the spinal curvature angle according to an inflection point of the spinal curve. The spinal curvature angle measurement method can enable the three-dimensional ultrasonic imaging technique to measure the spinal curvature angle. Through the manner for acquiring the curve points manually, or the manner for acquiring the curve points by a computer-assisted method, or combination of the two manners, the accuracy of spinal curvature angle measurement can be improved.

Description

technical field [0001] The invention relates to the medical field, and more specifically relates to a method for measuring the curvature angle of the spine, which is applied to medical imaging equipment. Background technique [0002] The spine is made up of twenty-four vertebrae and intervertebral discs. Its normal curvature gives the spine its flexible, elastic, and shock-absorbing properties. However, scoliosis is a musculoskeletal condition in which the spine abnormally bends sideways, causing the spine to tilt to the left. Or right-curved, the spine with scoliosis looks like an S or C letter because of the abnormal curvature, when the spine fails to develop its normal front-to-back arch, placing abnormal weight on the intervertebral discs. Scoliosis is most commonly associated with adolescence, with kyphosis, a visible spinal deformity associated with scoliosis, in which the spine is curved at an angle of forty-five degrees or more in the upper back region, compared to a...
