采用基于小波金字塔分解的方法对颅颌面CT MRI医学图像进行融合 ,再经可视化技术处理 ,以测量和分析颅颌面部各咀嚼肌的三维肌力向量。结果显示 :咀嚼肌系统在功能状态下具有不同大小的生理横截面积和最大肌力 ,不同咀嚼肌以及同一咀嚼肌的不同侧别其肌力的空间方向亦各不相同。提示借助于颅颌面CT MRI医学图像融合技术获得咀嚼肌的三维肌力向量是可行的 ,这将为咀嚼肌系统的基础研究提供有意义的研究结果
Based on wavelet pyramid decomposition, the MRI medical images of cranio-maxillofacial CT images were fused and then processed by visualization technique to measure and analyze the three-dimensional muscular force vector of the craniomaxillofacial regions. The results showed that the masticatory system had different physiological cross-sectional area and maximum muscle strength in different functional states, and different masticatory muscles and different side of the same masticatory muscle had different spatial directions of muscle strength. It is feasible to obtain the three-dimensional muscular force vector of the masticatory muscles with the help of the craniomaxillofacial CT MRI medical image fusion technology. This will provide a meaningful research result for the basic research of the masticatory muscle system
