基于最大互信息的PET／CT图像配准方法研究

Research on maximal mutual information of PET/CT registration

针对最大互信息的多模医学图像配准方法进行分析和研究，描述在PET／CT医学图像配准过程中涉及的插值方法和优化算法，对实验采用三线性PV插值和Powell优化搜索算法，能够快速、准确地实现多模医学图像的配准。

This paper analyses and studies the methods of PET/CT registration based on maximal mutual information. It also describes related interpolation and opt/mization methods. In this experiment, it obtains accuracy and fast muhi-modality medical image registration by using TRI PV interpolation and Powell algorithm.
