运动员因剧烈运动常导致隐性骨骼损伤，常规的CT图像观测方法靠人工经验判断，无法有效发现隐性骨骼损伤的CT图像断点，不能形成合理的诊断方案，断点标定性能较差。提出一种基于模板叠加和相异特征匹配的CT图像断点标定方法，进行基于小波变换的CT图像边缘检测分离，采用相异特征匹配的方法消除图像中的噪点信息，提取灰度像素值特征，根据Shannon信息论原理，描述融合结果与源图像的综合相关性信息，得到CT源图像与断点融合图像的进行相关性标定，采用模板叠加和相异特征匹配得到准确的断点标定结果。实验证明，采用该算法能有效实现对CT图像的隐性损伤骨骼损伤作出的断点标定，标定的准确度较高，鲁棒性好，抗噪性优越。为体育运动损伤诊疗提供理论依据。

The athletes from strenuous exercise often leads to the recessive skeletal injury, the conventional method of CT image observations by artificial experience, cannot effectively find CT image breakpoint recessive skeletal injury diagnosis, reasonable scheme cannot be formed, it has the poor performance of the breakpoint calibration. A method is proposed to cal?ibrate the CT image matching template superimposed breakpoint and distinctive features based on separation, CT image edge detection based on wavelet transform, methods using different feature matching to eliminate image noise information, extracted from the gray level pixel values, according to the Shannon information theory, it describes the correlation with the source image information fusion results get the correlation, calibration and image of the breakpoints CT source image fu?sion, using template superposition and distinct feature matching to obtain accurate breakpoint calibration results. Experi?ments show that the algorithm can effectively achieve the CT image of recessive injury of skeletal injury of the breakpoint calibration, the calibration accuracy is improved, it has good robustness and excellent anti noise performance. It provides a theoretical basis for the diagnosis and treatment of sports injuries.
