1. A non-transitory computer-readable medium storing computer-executable instructions that, when executed, cause a processor to perform operations, comprising:
accessing an image volume of a rectum comprising a rectal tumor;
generating a forward mapping based on non-rigidly registering a healthy rectal atlas to the image volume;
inverting the forward mapping to generate an inverse mapping from the image volume to the healthy rectal atlas;
determining, based on the inverse mapping, a plurality of deformation vectors associated with a deformation within a rectal wall of the rectum;
computing magnitude based deformation features from the plurality of deformation vectors;
computing orientation based deformation features from the plurality of deformation vectors; and
utilizing one or more of the magnitude based deformation features and one or more of the orientation based deformation features to determine a response of a patient to a chemoradiation treatment.
