  • Patent number: 6826423
    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.

  • Patent number: 6240308
    Abstract: Method and apparatus for archiving and simultaneous display of brain scan images and a plurality of brain maps. The brain maps are proportioned to the individual brain of the scan images by a three-dimensional alignment process. Two-dimensional and three-dimensional displays are supported.

  • Patent number: 6011828
    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.

  • Patent number: 5640496
    Abstract: Method and apparatus for management of image data using dynamic image pixel management for composite image display of image data so that "overlayed" and transparent images may be displayed, changed, and redisplayed in real time. On redisplay, the invention returns values of only those pixels, the values of which have changed, or any subset of all pixels. The invention is independent of the hardware used to display images and permits true color with transparency regardless of the number of display hardware bit planes available.

  • Patent number: 5398684
    Abstract: The disclosure is directed to a method and apparatus for presenting a plurality of scanning images in a video presentation. The disclosure is particularly directed to the use of such an apparatus and method in stereotactic surgery, wherein acquisition of a plurality of scanner images, conversion of these images into a selected standard format, storage of the acquired and converted images, selective recall and display of at least two of the images, and independent manipulation of each of the images for comparison are provided. Probe placement can be simulated and the images can be enhanced in various ways. The images used can be, for example, CT, PET, X-ray, DSA, isotope, and NMR scans. Brain map atlas images can be superimposed on and fitted to the scan images of a particular brain. Video displays of three dimensional simulations can also be produced.

  • Patent number: 5354314
    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.

  • Patent number: 5339812
    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.
