Abstract: An apparatus and method for aligning and imaging a body part which immobilizes the body part within a stereotactic body localization system having an imaging resolver fiducial localizer for precise imaging and localization of the body parts within the apparatus. Both anterior and posterior immobilization methods can be used. A continuous array of coupled fiducials is employed with at least one pair formed in a &pgr;/2 horizontal linked sine and cosine wave fiducial pattern.

Abstract: An apparatus and method for aligning a radiosurgery/stereotactic radiotherapy system. The system includes a linear accelerator, including a gantry and a collimator, a couch, and a stereotactic reference system mounted on the couch. The apparatus includes a laser measuring device mounted on the gantry, the laser measuring device having a laser generator element for generating a laser light beam and a laser displacement sensor. The apparatus also includes a reference fixture, attached to the stereotactic reference system, having at least one reflective surface for reflecting the laser light beam to the laser displacement sensor, upon which the laser displacement sensor measures the distance between the reflective surface and the laser measuring device.

Abstract: A method and apparatus for determining, in three dimensions, the location, size, depth and width of tumors, lesions, abnormalities, structures, and the like, particularly useful for stereotactic surgery. The invention utilizes several energy beams which, when they intersect, allow for such measurements and calculations. In one embodiment, the energy sources attach to a stereotactic frame. In an alternative embodiment, the energy sources are incorporated within a stereotactic microscope. Either embodiment may be mounted on an articulated robotic type arm.

Abstract: An optimized dose delivery system using computer graphics simulation techniques and computerized numerical optimization. A volume, such as a tumor volume, is graphically simulated and meshed with node points. The dose delivery is calculated depending upon input variables, deriving an objective function related to dose efficacy. A numerical optimization algorithm optimizes the input variables based upon such objective function.
