A method for registering a source image of an object with a target image of the object includes generating a mask image delineating a structure of interest from the source image, determining a distance map for the mask image, determining a shape representation by identifying an iso-value on the distance map such that level curves correspond to the characteristics of a desired shape, iteratively calculating a similarity metric corresponding to a region of overlap between the level curve based shape representation and the second image resulting in a registration transform, applying the registration transform to the target image to co-register the source image with the target image, and displaying the co-registered source image and the target image on a display device.
