摘要
利用错切变形(shear-warp)算法对离体牙的光学相干层析图像进行三维重建，实现牙齿三维组织结构的可视化，便于医生对病变进行定位，为早期的龋齿诊断提供依据。介绍了shear-warp算法的原理、用于龋齿检测的全光纤光学相干层析成像系统，以及使用该系统扫描得到97幅离体牙牙冠的二维层析图并重建获得三维结构图。
Abstract
The shear-warp algorithm is used to reconstruct optical coherence tomography images (OCT) of the tooth in vitro. 3D reconstruction image is convenient for doctors to locate lesions and has a great potential for the clinical diagnosis of early dental caries. The basic principle of the shear-warp algorithm is introduced, as well as the all-fiber optical coherence tomography dental diagnosis system and three dimensional reconstruction image of the tooth in vitro based on 97 OCT images.
