非刚性医学图像配准研究综述

非刚性配准技术是医学图像配准中的一个重要研究课题,是非刚性组织配准,不同个体之间的配准以及个体同图谱配准的基础。该文提出了多项式法、样条函数法等基于空间变换的配准方法,以及弹性模型、粘性流体模型和光流场模型等基于物理模型的配准方法两大类方法。同刚性配准相比,非刚性配准技术还不成熟,计算效率和稳定性还需要进一步提高,仍是一个非常活跃的研究领域。

A Survey of Non-rigid Medical Image Registration

Non-rigid image registration is an important problem of medical image analysis,and the basis of distortion organ registration,intra -patient registration and altas registration.A number of methods such as polynomials based approach,splines based approach,elastic model,viscous fluid model and optical flow model etc have been developed for this problem.Contrasted with rigid registration,non-rigid registration is not mature,and still an active research field.
