摘要： The invention comprises an apparatus and method of use thereof for generating a rare earth from a rare earth oxide, comprising the steps of: (1) dissociating the rare earth oxide and hydrogen gas in a reaction chamber by inductively heating the reaction chamber to greater than 2000° K to form the associated rare earth and water vapor in a reaction process; (2) driving the reaction process forward by removing the water vapor from the reaction chamber by condensing and freezing the water vapor on a first cold trap surface as water ice, where the reaction comprises: RE2O3+3H2→2RE+3H2O, where REO is a rare earth oxide and RE comprises a rare earth in the rare earth oxide; and/or (3) monitoring the reaction process by monitoring generation of at least one of the rare earth and the water in a control system designed for continuous/semi-continuous operation.

摘要： Generally, a method or apparatus for tomographically imaging a sample, such as a tumor of a patient, using positively charged particles positions n two-dimensional detector arrays on n surfaces of a scintillation material or scintillator, respectively. Resultant from energy transfer from the positively charged particles, secondary photons are emitted from the scintillation material and detected by the plurality of two-dimensional detector arrays, where each detector array images the scintillation material. Combining signals from the plurality of two-dimensional detector arrays, the path, position, energy, and/or state of the positively charged particle beam as a function of time and/or rotation of the patient relative to the positively charged particle beam is determined and used in tomographic reconstruction of an image of the sample or the tumor.

摘要： The invention comprises a method and apparatus for determining a radiation beam treatment path to a tumor, comprising the steps of: (1) delivering charged particles from an accelerator, along a first beam transport path, through an output nozzle, and along a treatment path to the tumor relative to a calibrated reference beam path from the output nozzle toward a patient position and (2) prior to the step of delivering, a main controller verifying an unobstructed linear path of the treatment path using a set of fiducial indicators positioned at least: on a first element physically affixed and co-movable with the output nozzle and on a moveable object in the treatment room. Optionally, voxels of the treatment beam path and potentially obstructing objects are defined in the treatment room using an axis system relative to the calibrated reference beam path and a reference beam point.

摘要： 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.

摘要： The invention comprises a method and apparatus for tracking and/or imaging impact of a particle beam treating a tumor using one or more imaging systems positionable about the tumor, such as a positron emission tracking and/or imaging system, where resulting tracking/imaging data: dynamically determines a treatment beam position, tracks a history of treatment beam positions, guides the treatment beam, and/or images a tumor before, during, and/or after treatment with the charged particle beam.

摘要： The invention comprises a fiducial marker—fiducial detector based treatment room position determination/positioning system apparatus and method of use thereof. A set of fiducial markers and fiducial detectors are used to mark/determine relative position of static and/or moveable objects in a treatment room using photons passing from the markers to the detectors. Further, position and orientation of at least one of the objects is calibrated to a reference line, such as a zero-offset beam treatment line passing through an exit nozzle, which yields a relative position of each fiducially marked object in the treatment room. Treatment calculations are subsequently determined using the reference line and/or points thereon. The treatment calculations are optionally and preferably performed without use of an isocenter point, such as a central point about which a treatment room gantry rotates, which eliminates mechanical errors associated with the isocenter point being an isocenter volume in practice.
