CT与MRI图像融合技术在颅颌面部的应用

APPLICATION OF CT AND MRI FUSION IMAGE TECHNOLOGY IN CRANIOFACIAL REGION

采用基于轮廓特征的奇异值分解 迭代最近点的配准方法和基于小波金字塔分解的融合方法进行颅颌面CT MRI医学图像的融合。结果显示 ,该融合操作简便快捷、图像满意、可靠性好 ,获得了颅颌面的CT和MRI的融合图像。提示在临床实践中颅颌面CT MRI医学图像的融合是可行的 ,可以从解剖结构复杂的颅颌面部图像信息中获得有利于诊断和治疗分析的图像依据。

To achieve the fusion of cranio-jaw-facial CT and MRI image,the single value decomposition-iterative closest point method based on contour feature and the multiresolution method based on wavelet pyramid were used.The results showed that the fusion was operated easily and promptly,its images were satisfactory and its reliability was good. The fusion of cranio-jaw-facial CT and MRI image was obtained. It suggested that the fusion of cranio-jaw-facial CT and MRI image was feasible in clinical practice. It can provide the image basis helping the analysis of diagnosis and treatment for diseases of the cranio-jaw-facial region with complicated anatomical formation.
