  • Patent number: 10556126
    Abstract: The invention comprises a method for generating a procedure for treating a tumor of a patient using positively charged particles, comprising the steps of: (1) providing a set of treatment goal specifications; (2) generating tomographic images of the tumor using a first set of groups of the positively charge particles delivered from a synchrotron; and (3) a computer implemented algorithm automatically generating a tumor radiation treatment plan, of the tumor using the positively charged particles, using the set of treatment goal specifications and the tomographic images. Optionally, the method automatically updates the radiation treatment plan upon: a detected movement of the tumor relative to surrounding patient constituents and/or upon detection of a previously unforeseen intervening object in a treatment beam path.

  • Patent number: 10555710
    Abstract: The invention comprises a method and apparatus for imaging a tumor with X-rays while, simultaneously or alternatingly, treating or imaging the tumor with positively charged particles. An X-ray imaging system, such as one or two sets of a cone beam X-ray source coupled to an X-ray detector, is rotatable about a first axis and a patient. The X-ray imaging system is positioned off axis a path of charged particles delivered through an exit port of a nozzle system from a synchrotron and does not block a path of the positively charged particles from the exit nozzle to the patient or an imaging path from the patient to a scintillation detector. Fiducial indicators are used to confirm an unobstructed path of the positively charged particles in a treatment room comprising many movable elements, such as the X-ray imaging system and a patient positioning system/couch.

  • Patent number: 10549124
    Abstract: The invention comprises a method and apparatus for treating a tumor with protons using multiple beamline positions not having an isocenter, including the steps of: (1) delivering the protons from a synchrotron along a redirectable beam transport path to yield a plurality of incident vectors, each of the plurality of incident vectors directed toward the treatment room and (2) redirecting the protons traveling along each of the plurality of incident vectors, with an output nozzle, to the tumor, where a first vector, of the plurality of incident vectors, comprises a first direction intersecting the tumor and where a second vector, of the plurality of incident vectors, comprises a second direction passing by the tumor without entering the tumor. The step of redirecting directs the protons traveling along the first and second incident vectors, respectively, to a first and second path intersecting a front and the back of the tumor.

  • Patent number: 10376717
    Abstract: The invention comprises a method and apparatus for treating a tumor using positively charged particles having passed through an intervening object, comprising the steps of: predetermining an energy reduction of the positively charged particles resultant from the positively charged particles traversing the intervening object along a beam treatment path as a function of relative rotation of the patient and the beam treatment path; generating a radiation treatment plan adjusting energy of the positively charged particles delivered from the synchrotron to the intervening object to yield a desired beam treatment energy of the positively charged particles entering the tumor after compensating for the energy reduction; and optionally detecting a set of the positively charged particles after traversing the intervening object to yield a signal, where the signal is used with knowledge of energy of the positively charged particles exiting the synchrotron to pre-determine the energy reduction along the beam treatment pat

  • Patent number: 10323298
    Abstract: A single-heating stage method for reclaiming or recovering metals like nickel and vanadium from a petroleum waste byproduct has three steps: melting the petroleum waste byproduct in a reducing atmosphere, generating agglomerated metal in the melted byproduct, and lifting the agglomerated metal to an exposed surface of the melted byproduct. The metal precipitates out of the molten byproduct, agglomerates into a separate portion, and rises to an exposed surface of the melted petroleum waste byproduct even though the metal may have greater density than the molten petroleum waste byproduct. The original petroleum waste byproduct stratifies into a byproduct remnant and the agglomerated metal disk. The agglomerated metal disk is separable from the byproduct remnant and may be additionally separated into constituent metals in those embodiments with multiple metals in the disk.

  • Patent number: 10279198
    Abstract: A scintillation material is longitudinally packaged in a circumferentially surrounding sheath, where the sheath has a lower index of refraction than the scintillation material, to form a scintillation optic or scintillation fiber optic. The scintillation material yields secondary photons upon passage of a charged particle beam, such as a positively charged residual particle beam having transmitted through a sample. The internally generated secondary photons within the sheath are guided to a detector element by the difference in index of refraction. Multiple scintillation optics are assembled to form a two-dimensional scintillation array coupled to a two-dimensional detector array, such as for use in determination of state of the residual charged particle beam, determination of an exit point of the particle beam from the sample, path of the treatment beam, and/or tomographic imaging.
