Fusion Algorithm of Functional Images and Anatomical Images Based on Wavelet Transform

摘要

Fusion problem of medical functional images and anatomical images is studied in this paper. Based on wavelet multi-scale decomposition the fusion algorithm of functional images and anatomical images is advanced and elaborated, and the method of fusion rule selection is summarized in detail. Using the algorithm, a PET image and a MRI image of a brain are merged. With the index integrating entropy and cross entropy, the fusion result is assessed indicating the validity of the algorithm and the method.
