1. A method for evaluating at least one image data record of a region of a patient including at least one joint, that the method comprising: recording the at least one image data record of the region; segmenting the recorded at least one image data record with respect to at least one mechanically relevant component of the joint in order to determine segmentation information; at least one of generating a patient movement model based upon the determined segmentation information, wherein a closest database movement model is determined by comparison with a database comprising a plurality of different movement models and wherein the patient movement model is complemented by transferring information, missing in the patient movement model, from the database movement model, and selecting the patient movement model from a database of movement models, wherein a closest corresponding movement model is selected from the database with respect to the segmentation information of the anatomy of the patient as the patient movement model; and determining joint information relating to the motions of the joint from the at least one of the generated and selected patient movement model.
