Patent abstract
A method for registering 2-D radiographic images to 3-D volume studies includes generating digitally reconstructed radiographs (DRRs) from a 3-D volume study. The DRR's are used as reference images to register a patient's position during image-guided radiosurgery. Stereoscopic X-rays of the patient are acquired during treatment, and multi-phase registration is used to register the DRRs with the X-ray images in two or more projections.
