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.

Abstract: The disclosure is directed to 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 light beams which, when they intersect, allow for such measurements and calculations. In one embodiment, the light sources attach to a stereotactic frame. In an alternative embodiment, the light sources are incorporated within a stereotactic microscope.
