Patent number: 10792517Abstract: The invention comprises a method and apparatus for determining state of a positively charged particle, such as a proton, for use in imaging a tumor of a patient prior to and/or concurrent with cancer therapy. The imaging system comprises: (1) a beam transport path of the positively charged particle sequentially passing through a patient, through a first time of flight detector, and, after traversing a pathlength, at least into a second time of flight detector and (2) a beam state determination system using elapsed time between detection at the first and second time of flight detectors and the pathlength to determine a residual beam energy, which, when compared to a known incident beam energy, is used in generation of an image of the tumor. An optional beam energy degrading element increases time differences between the time of flight detectors.Type: GrantFiled: November 27, 2017Date of Patent: October 6, 2020Inventors: W.

Patent number: 9937362Abstract: The invention comprises a beam adjustment method and apparatus used to perform energy adjustments on circulating charged particles in a synchrotron previously accelerated to a starting energy with a traditional accelerator of the synchrotron. The beam adjustment system uses a radio-frequency modulated potential difference applied along a longitudinal path of the circulating charged particles to accelerate or decelerate the circulating charged particles. Optionally, the beam adjustment system phase shifts the applied radio-frequency field to accelerate or decelerate the circulating charged particles while tightening spatial distribution of a grouped bunch of the circulating charged particles. Optionally, the beam adjustment system simultaneously radially focuses the circulating charged particles using two or more gaps with focusing and/or defocusing edges.Type: GrantFiled: October 25, 2016Date of Patent: April 10, 2018Inventors: W.

Patent number: 9855444Abstract: The invention comprises a method and apparatus for probing a tumor of a patient using positively charged particles, comprising the steps of: (1) sequentially delivering sets of varied and known positively charged particles to a patient; (2) after transmission through the patient, sequentially detecting a residual energy of each of the sets of positively charged particles; and (3) determining a water equivalent thickness of a probed path of the patient using a plot of the detector response as a function of residual energy that is fit with a curve. The analyzer relates a half maximum of the fit curve, such as a Gaussian curve, to the water equivalent thickness of the sampled beam path. Repeated measurements as a function of incident angle and/or position of the incident charged particles allows generation of an image of the sample, such as a computed tomography image.Type: GrantFiled: November 10, 2016Date of Patent: January 2, 2018Inventors: Scott Penfold, W.

Publication number: 20170216632Abstract: The invention comprises a method and apparatus for directing a positively charged particle beam to a tumor of a patient, comprising the steps of: (1) transporting the positively charged particle beam sequentially from a synchrotron, through a beam transport line, and through a nozzle system toward the tumor, the beam transport line comprising a rotatable beamline section; (2) pre-rotating the positively charged particle beam using a solenoid, the solenoid positioned in the beam transport line between the synchrotron and the rotatable beamline section; and (3) rotating the rotatable beamline section, where the step of pre-rotating maintains a geometric relationship between a radial cross-section of the positively charged particle beam and magnet surfaces in the rotatable beamline section as a function of rotation of the rotatable beamline section, which reduces otherwise changed dispersive forces as the rotatable beamline is positioned in separate areas about the patient.Type: ApplicationFiled: April 17, 2017Publication date: August 3, 2017Inventors: W.

Publication number: 20170128747Abstract: The invention comprises an X-ray—positively charged particle double/dual exposure imaging apparatus and method of use thereof. Double exposure imaging of a tumor of a patient is performed using detector hardware responsive to both X-rays and positively charged particles. A near-simultaneous double exposure yields enhanced resolution due to the imaging rate versus patient movement, no requirement of a software overlay step of the X-ray based image and the positively charged particle based image, and enhancement of an X-ray image, the enhancement resultant from a differing physical interaction of the positively charged particles with the patient compared to interactions of X-rays and the patient. Further, resolution enhancements utilize individual particle tracking, as measured using detection screens, to determine a probable intra-patient path.Type: ApplicationFiled: January 23, 2017Publication date: May 11, 2017Inventors: James P. Bennett, Kyle Schmanke, Lauri Reichert, Stephen Sledge, Nick Ruebel, Jillian Reno, Edward Ivanov, Mark R. Amato, Scott Penfold, W. Davis Lee
