Abstract
Apparatus, methods, and other embodiments associated with evaluating global deformations and local deformations in a prostate are described. One example apparatus includes logics that evaluate global and local deformations in a prostate and register a pre-External Beam Radiation Treatment (EBRT) three dimensional (3D) magnetic resonance (MR) image with a post-EBRT 3D MR image. An image acquisition logic acquires a pre-EBRT image and a post EBRT image of an organ, item, or volume. An image texture information logic extracts image texture information from the pre-EBRT and post-EBRT images. A finite element model (FEM) transformation logic constructs a FEM of the volume imaged in the pre-EBRT image, deforms the FEM, deforms the pre-EBRT image as a function of the deformed FEM, and maximizes the image texture similarity between the deformed pre-EBRT image and the post-EBRT image. A registration logic registers the pre-EBRT image with the post-EBRT image based on the transformation.
