Abstract

This paper presents a mutual-entropy-based global registration method for temporal subtraction of chest radiographs. Our global registration method consists of two steps. In the first step, we make a rough registration by calculating the mutual entropy of on the whole areas of the previous radiograph and the current radiograph, and in the second step, we make an accurate registration by calculating the mutual entropy of on the rib areas only. Experimental results demonstrated that the visualization of pathological change in the temporal subtraction images constructed by our global registration method is better than that constructed by convenient global registration methods.
