  • Publication number: 20120041685
    Abstract: Systems and methods for accurately calculating radiation doses in biological tissues exposed to a radiation source are provided. In the systems and methods first, a radiation dose is computed to geometry of water equivalent medium of the biological tissues, expressed in computed tomography (CT) volumetric images. A Medium-Dependent-Correction factor that is a function of an effective bone depth matrix and the incident x-ray beam is obtained and tabulated. Using patient material and density data derived from CT images, the effective bone thickness can be calculated from a specific x-ray source. Finally, a Medium-Dependent-Correction factor that is a function of an effective bone depth matrix is used to accurately determine the radiation dose distributions to biological tissues.

  • Publication number: 20120010601
    Abstract: A method of treating diseased tissue in a patient, the diseased tissue being proximate a hardened previously implanted bone cement including relatively high atomic number elements in a patient. The method includes generating a photon beam and directing the generated photon beam into the patient in a direction such that at least a portion of the photon beam impinges on the hardened bone cement and generates Compton interaction knock-out electrons from the high atomic number elements included in the hardened bone cement as a result of interaction of the at least a portion of the photon beam with the bone cement, wherein the direction of the photon beam is such that the at least a portion of the photon beam impinges on the hardened bone cement so that at least some of the Compton interaction knock-out electrons impinge upon the diseased tissue.
