摘要

描述一种正常的基于方向的方法来跟踪心脏运动。首先，插值两个切片之间的空间来重建局部区域。然后，该方法将三维曲面扩展为一个框架，并将框架的每个单元属性化为其法向量。通过改变属性参数，生成角度图，并对角度图应用改进光流法估计可变形曲面的二维运动矢量场。

Human heart motion analysis through normal flow methods [SPECT image analysis]

Describes a normal direction-based method to track heart motion. First, the space between two slices is interpolated to reconstruct the local region. Then the method expands the 3-dimensional surface to a frame, and attributes each cell of the frame with its normal vector. Through changing the parameter of the attribute, it generates angle maps and applies modified optical flow method to the angle maps to estimate the 2-dimensional motion vector field of the deformable surface.<>
