1. A method comprising:
receiving, for each patient of a set of patients, preoperative imaging data of a first imaging modality and intraoperative imaging data of a second imaging modality;
registering, for each patient of the set of patients, the preoperative imaging data of the first imaging modality to the intraoperative imaging data of the second imaging modality;
registering preoperative imaging data of each patient to preoperative imaging data of other patients;
registering different deformations of the set of patients into a common deformation space, yielding different possible deformations;
generating a set of deformation models representing the different possible deformations;
applying each deformation model of the deformation models to preoperative imaging data of a new patient to obtain deformed imaging data for each deformation model;
comparing, for each deformation model, the deformed imaging data to intraoperative data of the new patient; and
determining the deformation model that best fits the intraoperative imaging data of the new patient based on the comparing.
