摘要
Technologies described herein generally provide for an improved augmented reality system for providing augmented reality images comprising a pre-operative image superimposed on a patient image. The accuracy of registering the pre-operative image on the patient image, and hence the quality of the augmented reality image, may be impacted by the periodic movement of an organ. Registration of the pre-operative image on the patient image can be improved by accounting for motion of the organ. That is, the organ motion, which can be described by a dynamical model, can be used to correct registration errors that do not match the dynamical model. The technologies may generate a sequence of 3-D patient images in real-time for guided surgery.
