  • Monte Carlo evaluation of a Compton camera in breast and brain imaging

    Uche, Chibueze Zimuzo; Round, W. Howell; Cree, Michael J. (Springer, 2013)
    Background: The Compton camera is increasingly becoming the subject of investigation for possible implementa- tion in nuclear medical imaging. It is likely to have advantages over Anger camera in medical imaging. However, ...
  • A Monte Carlo evaluation of three Compton camera absorbers

    Uche, Chibueze Zimuzo; Round, W. Howell; Cree, Michael J. (Springer, 2011)
    We present a quantitative study on the performance of cadmium zinc telluride (CZT), thallium-doped sodium iodide (NaI(Tl)) and germanium (Ge) detectors as potential Compton camera absorbers. The GEANT4 toolkit was used to ...
  • A Monte Carlo study of two Compton camera’s first plane detectors

    Uche, Chibueze Zimuzo; Round, W. Howell; Cree, Michael J. (Springer, 2011)
    Purpose: The suitability of two possible detectors, silicon and germanium as the Compton camera’s first plane detector has been investigated using a robust Monte Carlo approach. Methods: The GEANT4 simulation software was ...
  • Optimizing Compton camera performance

    Uche, Chibueze Zimuzo (University of Waikato, 2011)
    Amore realistic simulation approach is used to study the behavior of the Compton camera in this thesis than previous studies to date. The Compton camera differs from gamma cameras in that the collimator is replaced by a ...
