摘要: 提出了一种基于光流场的医学图像弹性配准方法。方法先对图像进行小波分解,从最低分辨率的近似图像开始,采用光流场的方法进行逐级配准,再对配准的各分量进行重构,直至得到最高分辨率的配准图像。实验表明,这种方法对于具有较小形变的医学图像的配准是有效的。

Abstract: An elastic registration technique for medical image based on optical flow field is presented in this paper.In this method,from the lowest resolution,the approximate images are registered by optical flow field,and then reconstruct the image,up to the highest resolution.The experiments show this method is effective for medical image with less deformation.

Key words: medical image, wavelet transformation, optical flow field, elastic registration
