A Medical Image Fusion Method Based on Image Segment

QU Guihong, ZHANG Dali, YAN Pingfan. Department of Automation, Tsinghua University, Beijing 100084  
A novel method for medical image fusion is proposed. It can be used to define lesion focus during treatment planning. Edge detection is studied by using an improved Canny edge detector, and threshold for non interesting region is made by calculating local image histogram. Space mapping is built by image registration. Features of lesion focus in an image can then be overlaid with other corresponding images and a fused image with features of edge of lesion focus and anatomic structure can be obtained. Results of experiments showed that the proposed method is simple and intuitive, and can be used in clinical application very well.
