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.

Description

RELATED APPLICATION

[0001] This application is a continuation in part of U.S. patent application Ser. No. 09 / 270,404, filed Mar. 16,1999 entitled “Apparatus and Method for Compensating for Respiratory and Patient Motion During Treatment” which is owned by the same assignee as the present invention and is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] This invention relates generally to a system and method for treating a patient and in particular to a system and method for controlling a treatment to administer a precise dose to a patient. In more detail, the invention relates to an apparatus and method for performing accurate surgical procedures on a particular target region within a patient utilizing previously obtained reference data indicating the position of the target region with respect to its surrounding which may contain certain reference points.

[0003] In order to control a surgical procedure, such as radiosurgery, many different prior techniques have be...

Embodiment Construction

[0028] The invention is particularly applicable to a radiosurgical treatment system and method and it is in this context that the invention will be described. It will be appreciated, however, that the system and method in accordance with the invention has greater utility, such as to other types of treatments wherein it is necessary to accurately position a treatment at a target region within the patient in order to avoid damaging healthy tissue such as to other types of medical procedures with other types of medical instruments, such as positioning biopsy needles, ablative, ultrasound or other focused energy treatments, positioning a laser beam for laser beam treatment or positioning radioactive seeds for brachytherapy. Prior to describing the invention, a typical radiosurgery device will be described to provide a better understanding of the invention.
