A system () visualizing an image registration mapping in an intuitive interactive manner. The system () includes a display () and one or more processors (). The processors () are programmed to receive a first image and a second image and obtain an image registration mapping from the first image to the second image. Even more, the processors () are programmed to display the first image adjacent to the second image on the display () and obtain one or more reference image locations. Each of the reference image locations is defined in the coordinate frame of one of the first image and the second image. Moreover, the processors () are programmed to highlight each of the reference image locations on the one of the first image and the second image and highlight a correlated image location for each of the reference image locations in the other one of the first image and the second image. The correlated image locations are determined using the image registration mapping.

Deformation maps (e.g. deformation vector fields) used for correcting image-type data used in the treatment of patients in radiotherapy may be processed to eliminate inverse inconsistency and transitivity type errors which produce different results depending on the order or path of the calculation of deformation. The correction permits registration of a treatment plan with the changing patient image and accumulation of dose to a common reference frame without transformation dependent artifacts.
