N2 - Image registration is a central field in biomedical image analysis. Despite the large body of work on automatic image registration algorithms, in practice, results are often imperfect and can benefit from manual editing. In the current study, we propose a novel interactive registration tool that can be used for editing and refinement of automatic image registration results. The method is based on displacements to control points applied by the user to a finite element mesh representation of an organ of interest. The user-applied-displacements are translated to local forces using the organ’s elastic properties. The local user-derived forces are applied on the mesh and deform the image accordingly. We test the current method on 2D x-ray hand simulated data with non-continuous motion field and on 3D cardiac CT image data.
