超声和MR/CT图像的非刚性配准技术

Registration of Ultrasound and MR/CT Images

刚性或近似刚性图像配准的研究已在神经导航领域获得了实际意义的临床应用。相比之下,非刚性图像配准的研究则比较薄弱,尤其是像超声和MR/CT图像配准等多模态非刚性图像配准。本文总结了各种非刚性图像配准方法,着重于近年来用于超声和MR/CT图像配准的新方法,归纳这些方法的原理、创新性和优缺点,并展望超声和MR/CT图像配准技术的发展。

Rigid registration methods had been used in neuro-navigator guided surgical operation up to now. However, nonrigid registration methods still need further development and will have more wide application. This paper summarizes all kinds of non-rigid ultrasound and MR/CT registration methods, including their principles, innovations, advantages and limitations. Finally, future research and development of these methods are also discussed.
