  • Simulation and visualization of scattered radiation
    Patent number: 8552858
    Abstract: Scattered radiation has non-intuitive properties. A signalling system (28) is presented which provides a perceptible signal (34) being indicative of a predicted or measured spatial distribution of scattered radiation. An embodiment provides for easy assessment of the individual risk of scattered radiation exposure for personnel working in an environment exposed to scattered radiation. A method for predicting a distribution of scattered radiation takes into account at least one object related parameter (18) and at least one radiation related parameter (22) and, in response hereto, predicts a distribution of scattered radiation.
    Type: Grant
    Filed: February 22, 2008
    Date of Patent: October 8, 2013
    Assignee: Koninklijke Philips N.V.
    Inventors: Steffen Gunther Hohmann, Christian Baeumer, Joerg Bredno, Norbert Conrads, Olivier Ecabert, Klaus Juergen Engel, Christoph Herrmann, Rainer Kiewitt, Helko Lehmann
  • METHOD AND APPARATUS FOR SCATTER CORRECTION
    Publication number: 20110060566
    Abstract: A method and apparatus of image reconstruction correcting for photon scatter is provided. A direct physical measurement of scattered photons is used in conjunction with a physical model of the photon scattering process to make the corrections.
