Abstract:
A system for determining a location of an anatomical target with reference to a medical apparatus, which comprises:a computer for storing and processing image scan data representing a patient's anatomy including an anatomical target, and referenced in image scan coordinates; a camera system for obtaining camera data of the patient's anatomy and the medical apparatus, and referenced in camera coordinates; a plurality of indexing elements mountable to the patient's anatomy and the medical apparatus, each indexing element detectable by the camera system to provide the camera data; means associated with the computer for correlating the image scan data and the camera data and for determining a location of the anatomical target with respect to the medical apparatus; and imaging means mounted in known relation to the camera system for providing image data of the patient's anatomy, and having comparative means associated with the computer for comparing image data with reconstructed image data derived from the image scan data to thereby facilitate the positioning of the anatomical target with the apparatus.
