Precise Registration of CT and MR Volumes Based on a New Creaseness Measure
Image registration or matching attempts to solve the problem that arises when two images taken at different times, by different sensors or from different viewpoints need to be compared. An upcoming application of image registration is in the field of medical images, specially since the introduction of 3-D modalities. Many methods have been proposed for multi-sensor medical image registration . Our research has focused in CT-MR registration because these modalities are widely available and they provide complementary information: CT depicts accurately bones, while MR distinguishes soft tissues.
