  • Planar and volumetric dosimeter with scintillating material for radiotherapy treatment using tomographic reconstruction
    Patent number: 9606242
    Abstract: According to one aspect, a planar and volumetric dosimeter for use with a radiotherapy machine having a radiation source. The dosimeter includes a scintillating assembly including a plurality of scintillating optical fibers and configured to generate a light output in response to incident dose distribution thereon from the radiation source, and a photo-detector operable to convert optical energy emitted by the scintillating assembly to electrical signals for determining actual two-dimensional (2D) or three-dimensional (3D) dose distribution incident on the scintillating assembly using a tomographic reconstruction algorithm.
    Type: Grant
    Filed: March 29, 2012
    Date of Patent: March 28, 2017
    Inventors: Luc Beaulieu, Luc Gingras, Mathieu Goulet, Louis Archambault

  • Fluence monitoring devices with scintillating fibers for X-ray radiotherapy treatment and methods for calibration and validation of same
    Patent number: 8610077
    Abstract: According to one aspect, a fluence monitoring detector for use with a multileaf collimator on a radiotherapy machine having an x-ray radiation source. The fluence monitoring detector includes a plurality of scintillating optical fibers, each scintillating optical fiber configured to generate a light output at each end thereof in response to incident radiation pattern thereon from the radiation source and multileaf collimator, a plurality of collection optical fibers coupled to the opposing ends of the scintillating optical fibers and operable to collect the light output coming from both ends of each scintillating optical fiber, and a photo-detector coupled to the collection optical fibers and operable to converts optical energy transmitted by the collection optical fibers to electric signals for determining actual radiation pattern information.
