Abstract
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.

29. A system for directing a treatment beam towards a patient, comprising:
-
a treatment bed to support the patient during a treatment; two or more diagnostic beam generators to generate diagnostic beams directed towards the patient during the treatment, the diagnostic beam generators being located at different predetermined positions, wherein a beam from each diagnostic beam generator is at a predetermined non-zero angle with respect to beams of the other diagnostic beam generators; an image recording device located adjacent the treatment bed to receive the diagnostic beams from the two or more diagnostic beam generators, wherein the image recording device is configured to capture the images from the diagnostic beams; and a respiratory motion detection system configured to determine the external movement of the patient during a respiratory cycle and to energize a treatment beam at a predetermined point in the respiratory cycle during the treatment. - View Dependent Claims (30, 31, 32)

33. A method for directing a treatment beam towards a target region in a patient, comprising:
-
generating a three-dimensional image of the patient prior to a treatment; determining a plurality of respiration cycles of the patient from external movement of the patient; energizing one or more diagnostic beams at a predetermined cycle time within one of the plurality of respiration cycles to locate the target region during the treatment; and energizing the treatment beam at the same predetermined cycle time during a subsequent one of the plurality of respiration cycles to treat the target region.

34. An apparatus for directing a treatment beam towards a target region in a patient, comprising:
-
means for generating a three-dimensional image of the patient prior to the treatment; means for determining a respiration cycle of the patient from external movement of the patient; means for energizing one or more diagnostic beams at a predetermined time during the respiration cycle to locate the target region during the treatment; and means for energizing a treatment beam at the same predetermined time during the respiration cycle to treat the target region. - View Dependent Claims (35, 36)
