  • High-speed tumor segmentation system
    Patent number: 8992405
    Abstract: A system for automatic segmentation of tumor tissue, useful for motion correction during radiotherapy using real-time imaging, identifies multiple regions based on the values of data and then identifies the tumors within the regions based on a priori knowledge about tumor size and/or location. The regions may be refined with robust and fast morphological operations, providing segmentation at speeds commensurate with the motion to be corrected.
    Type: Grant
    Filed: April 9, 2012
    Date of Patent: March 31, 2015
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Venkata Veerendranadh Chebrolu, Bhudatt R. Paliwal

  • Apparatus and method using synchronized breathing to treat tissue subject to respiratory motion
    Patent number: 7778691
    Abstract: Radiation treatment of the lung or surrounding tissue during continuous breathing is made possible by preparing a treatment plan linked to motion phase and then synchronizing the plan to motion phase as the patient follows a regular breathing schedule.

  • Method and apparatus for low dose computed tomography
    Patent number: 7688938
    Abstract: A computed tomography machine (1) provides for improved dose efficiency by calculating an optimized set of beam intensities to produce the desired image quality. Determination of the beam weights is based on an a priori modeling (53) of the properties of the patient being imaged.

  • Combined laser spirometer motion tracking system for radiotherapy
    Patent number: 7367955
    Abstract: An improved non-invasive respiration monitor combines signals from a spirometer and laser chest displacement sensor to reduce signal error. The improved respirations signal can be used for position correction in radiation therapy and imaging applications and can be displayed to a user in breath control techniques.

  • Treatment planning tool for multi-energy electron beam radiotherapy
    Patent number: 7202486
    Abstract: A stand-alone calculator enables multi energy electron beam treatments with standard single beam electron beam radiotherapy equipment thereby providing improved dose profiles. By employing user defined depth-dose profiles, the calculator may work with a wide variety of existing standard electron beam radiotherapy systems.

  • Radiation therapy volume phantom using film
    Patent number: 6974254
    Abstract: A volume phantom for radiation therapy verification employs film held in a spiral configuration within a equalizing ring of attenuating material. The ring provides improved uniformity in radiation measurement and may be extended, for example, to a hemisphere to provide improved modeling and simulation of treatments in the region of the head.
