AI Technical Summary
In existing technologies, the measurement accuracy and efficiency of two-dimensional imaging and manual three-dimensional information acquisition are low, making it difficult to meet the needs of large-scale clinical case analysis or rapid preoperative assessment.
By using a medical imaging-based method, the normal vectors of the talus and scaphoid bones are automatically calculated. The talonavicular coverage angle is obtained by using multi-directional projection and local curvature calculation of the point clouds on the surface of the talus and scaphoid bones, thus avoiding manual intervention and two-dimensional projection conversion.
It improves the repeatability and accuracy of measurements, reduces interference from changes in body position and differences in projection angle, and has greater applicability, meeting the needs of large-scale clinical case analysis and rapid preoperative assessment.
