【 中文摘要 】本发明公开了一种三维重建颞下颌关节的方法，所述方法是通过对颞下颌关节区域不同序列的磁共振数据进行融合，并根据融合后的数据进行三维建模，以最终获得一重建的颞下颌关节软硬组织；其中，所述磁共振数据包括斜矢状位数据和冠状位数据。本发明的方法通过多序列MRI图像识别和信息提取、融合技术，以较低的成本，针对感兴趣的区域，即颞下颌关节区域，准确、快速的获得原始数据量数倍的高质量磁共振图像数据，进而使用更加真实的数据进行三维重建。本发明可以克服磁共振数据量少、直接重建模型质量差及计算机模拟充填失真的缺点。

【 英文摘要 】The invention discloses a method for three-dimensionally reconstructing a temporal-mandibular joint. The method comprises the following steps of fusing magnetic resonance data of different sequences in a temporal-mandibular joint area, and performing three-dimensional modeling according to the fused data to finally obtain reconstructed temporal-mandibular joint soft and hard tissues, wherein the magnetic resonance data comprises oblique sagittal data and coronal data. According to the method, through multi-sequence MRI image recognition and information extraction and fusion technologies, high-quality magnetic resonance image data of which the original data size is several times of that of a temporal-mandibular joint area is accurately and rapidly obtained for the area of interest, namely the temporal-mandibular joint area, with low cost, and then three-dimensional reconstruction is performed by using more real data. The method can overcome the defects that the magnetic resonance data size is small, the direct reconstruction model quality is poor, and computer simulation filling distortion occurs.
