目的 利用 CT、 MR等获得的图像 ,重构出器官、 骨骼或组织的三维形体 ,帮助医生诊断、 治疗或制订手术方案。方法hear2Warp 算法通过将三维数据场的投影分解为错切变换( shear ) 和变形变换(warp)两步来实现三维重建 ,显著减少了计算量。先对体数据进行错切变换 ,然后在错切空间根据阈值法获取三维表面 ,根据光照模型得到三维表面的亮度 ,最后通过变形变换得到最终的结果图像。-The purpose of the use of CT, MR and other available images, reconstruct organs, bone or tissue of the three-dimensional shape, helping physicians diagnose, treat, or development of surgery. Methods hear2Warp algorithm the projection of three-dimensional data field is decomposed into shear transformation (shear) and deformation of transformation (warp) two-step to achieve the three-dimensional reconstruction, significantly reducing the computational complexity. The first body of data on the shear transformation, and then in the wrong tangent space under the threshold value method to obtain three-dimensional surface, obtained under the illumination model three-dimensional surface brightness, the final adoption of a final result of deformation of the image transformation.
