  • Patent number: 11285341
    Abstract: The present invention provides electron beam therapies with improved feedback control that delivers controlled and adjustable doses of electron beam radiation to variable shallow depths with little radiation exposure to both nearby tissues and tissues below the target. In order to control radiation to accurately penetrate to shallow depths and to allow the radiation to be adjusted to other depth settings in very small or even continuous increments, the present invention senses a plurality of different electron beam characteristics and then uses these to derive a composite characteristic, or analog, of the electron beam energy. The composite analog provides a strong correlation to energy that allows this precision. In another aspect, the present invention relates to implementing this feedback control by adjusting power levels used to establish the electron beam.

  • Patent number: 11135449
    Abstract: The present invention provides improved methods and apparatus that use machine vision techniques to rapidly and automatically guide objects into desired docking configurations. The present invention is based at least in part upon using multi-depth, rotationally symmetric targets that are observed from two or more observation perspectives. By taking advantage of parallax effects associated with the multi-depth topography of the target, the apparent positions of target features in captured image information encodes position and angular alignment of the objects relative to each other in three dimensional space. The practice of the present invention provides a fast, accurate, reliable and automatic approach to achieve hard or soft docking configurations in the electron beam therapies as well as to implement real-time gating and tracking during the course of a treatment.

  • Patent number: 9656098
    Abstract: The invention discloses a method of treating cancer in a patient, comprising administering to the patient a radiation sensitizer selected from nitroimidazoles in an amount effective to sensitize a patient to radiation and subjecting the patient to radiation therapy. In certain embodiments the radiation sensitizer is etanidazole or doranidazole.

  • Patent number: 8269197
    Abstract: The present invention relates to methods and systems for use of an electron beam system. The electron beam system may be used within a treatment center with very little radiation shielding. The electron beam system may be used in conjunction with low-z moderators that reduce the energy level of the electron beam without the need for complex or expensive energy control systems. The electron beam system may be used to treat skin cancer and dermatological patients in non-traditional treatment facilities, as well as invasive cancers, either in an unshielded operating room to deliver intraoperative radiation therapy (“IORT”) or in an unshielded room in the oncology department to deliver electron beam radiation treatment (“EB-RT”).
