David C. Westerly has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Areal modulator for intensity modulated radiation therapy
    Patent number: 8129701
    Abstract: A modulator for radiation therapy provides modulation of an area beam to decrease treatment time. Separate channels passing modulated “beamlets” are possible by spacing the channels such that spreading of the beams and multiple angles of treatment eliminate cold spots. The space between the channels allows well-defined channel walls and space for modulator mechanisms.
    Type: Grant
    Filed: February 27, 2008
    Date of Patent: March 6, 2012
    Inventors: Jihad H. Al-Sadah, David C. Westerly, Patrick M. Hill, Thomas R. Mackie
  • Ion radiation therapy system having magnetic fan beam former
    Patent number: 8076657
    Abstract: An improved beam forming system for ions used in radiation treatment employs a magnet system of successive quadrupole magnets to convert an ion pencil beam to a fan beam with reduced neutrons production compared with conventional beam spreading techniques using scattering foils.
    Type: Grant
    Filed: February 27, 2008
    Date of Patent: December 13, 2011
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Thomas R. Mackie, David C. Westerly
  • Scanning aperture ion beam modulator
    Patent number: 7977648
    Abstract: A modulator for ions such as protons employs multiple shutter pairs to create independently movable apertures effecting a multiple pencil beam treatment of the patient thereby increasing treatment speed by eliminating the need for a custom compensator.
    Type: Grant
    Filed: February 27, 2008
    Date of Patent: July 12, 2011
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: David C. Westerly, Thomas R. Mackie, Ryan T. Flynn
  • Phantom for ion range detection
    Patent number: 7714309
    Abstract: A phantom for heavy ion radiation therapy provides characterization of an ion beam that may enter but not exit from the phantom. The phantom may include multiple materials and multiple spatially dispersed ion detectors to obtain signals that may be fit to known beam curves to accurately characterize the location and other parameters of Bragg peak of a given ion beam within a patient.
