Title:

THREE-DIMENSIONAL-ULTRASOUND-BASED INTELLIGENT SCOLIOSIS COBB ANGLE MEASURING METHOD

Document Type and Number:

WIPO Patent Application WO/2023/197924

Kind Code:

A1

Abstract:

A three-dimensional-ultrasound-based intelligent scoliosis Cobb angle measuring method, belonging to the technical field of scoliosis diagnosing and screening and comprising the following steps: S1, using a three-dimensional ultrasonic system to acquire three-dimensional ultrasonic image information of the spine to form a three-dimensional spine image; S2, inputting the three-dimensional spine image obtained in step S1 into a computer system, and by means of the computer system, displaying, processing and analyzing the image information; and S3, the computer system identifying and extracting all spinous processes in the three-dimensional spine image and generating corresponding mark points, and then connecting all the mark points to form a spinous process connecting line, which consists of an upper straight line segment, an arc line segment and a lower straight line segment, making tangent L1 of the arc line segment at a transition point of the upper straight line segment and the arc line segment, and making tangent L2 of the arc line segment at a transition point of the lower straight line segment and the arc line segment. The angle α formed between tangent L1 and tangent L2 is a Cobb angle.
