A novel approach to ensure local rigidity and volume preservation with existing registration methods is presented. A modification to the deformation field is performed before application to the moving image. It adds little additional runtime and can be quickly implemented. Results are shown on T1 MR liver data with simulated enhancing structures to demonstrate the volume preserving properties.
