FRAMELESS RADIOSURGERY TREATMENT SYSTEM AND METHOD

A method and apparatus for selectively and accurately localizing and treating a target within a patient are provided. A three dimensional mapping of a region surrounding the target is coupled to a surgical intervention. Two or more diagnostic beams at a known non-zero angle to one another may pass through the mapping region to produce images of projections within the mapping region in order to accurately localize and treat the target wherein the images are captured using one or more image recorders.
