一种简单的医学图像刚体配准方法

A Simple Method for Medical Image of Rigid Registration

医学图像配准技术是当前医学图像处理研究的热点。从二维医学图像的刚体变换出发,针对单模态医学图像的配准,研究了基于投影的医学图像配准方法。该方法通过二值化参考图像和浮动图像,沿X轴和Y轴投影得到投影向量,然后根据投影向量元素的大小和位置,分别检测图像间旋转、平移运动的大小。仿真实验证明,该方法不失为一种简单有效的图像配准方法。

Medical image registration technique is a research hotspot of medical image processing these days. In this paper a rigid registration method was descried, which was intra - modality medical image registration based on projection. Projection algorithm is presented as follows： first, characterize the reference image and the float image and turn into binary images; then, project the binary images onto the X - axis and Y - axis and get the projection vectors; last, according to the elements of the vectors, the rotation and translation parameters were calculated separately. The method for image registration was proved to be simply and validated by the results of the simulation experiment.
