  • Water-equivalent two-dimensional detector methods, systems and apparatus for proton therapy
    Patent number: 10556130
    Abstract: A particle detection system for calibrating a particle therapy machine or validating a particle therapy plan. The detector system includes one or more two-dimensional particle detection layers for receiving a particle beam and one or more compensating layers. The compensating layer(s) are configured to adjust energy loss and scatter values introduced by the one or more two-dimensional particle detection layers to match water-equivalent values. Each compensation layer is positioned adjacent a respective one of the one or more two-dimensional particle detection layers.
    Type: Grant
    Filed: July 8, 2015
    Date of Patent: February 11, 2020
    Assignee: The Trustees of the University of Pennsylvania
    Inventors: Derek Dolney, Robert Hollebeek
  • Proton dose imaging method and apparatus
    Patent number: 10471279
    Abstract: Particle therapy systems and methods for particle dose imaging are provided. A particle therapy system includes a particle beam source for generating a particle beam; and at least one particle detector including an ionization chamber having a mesh electrode. The at least one particle detector is configured to receive the particle beam and to generate an ionization current responsive to the received particle beam. The ionization current may be used to characterize the particle beam.
