Summary: In image registration, one image is deformed to match another. Current techniques cannot account for local deformations in organ shape due to factors such as patient positioning, pathology, and individual anatomical differences between subjects. We propose to develop a registration method that allows for non-rigid local deformations, based on local optimization of information-theoretic measures and incorporating knowledge of the anatomy to constrain the registration process. A implementation of the method will be subject to a preliminary investigation of clinical utility. The method will help improve the accuracy of image analysis in many areas of clinical diagnosis, treatment and medical research.
