Abstract:

The invention comprises a method and apparatus for aligning a charged particle beam path for treating a tumor of a patient, comprising: a cancer therapy system comprising the charged particle beam path sequentially passing: from an injector, through a synchrotron, along a beam transport line, and through a nozzle; a first two-dimensional detector configured to measure a beam state of positively charged particles; and an integrated intelligent system configured to classify the beam state into a set of beam shape factors, the integrated intelligent system configured to correct the beam shape through application of a condition-action rule: (1) adjusting a first voltage delivered to a first magnet positioned in the beam line prior to the first two-dimensional detector and (2) altering the beam shape through application of a second voltage to a second magnet position in the beam line adjacent to the first magnet.

Abstract:

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.

Abstract:

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.

International Classification:

A61N 5/10

Abstract:

The invention comprises a method for treating a tumor of a patient with positively charged particles in a treatment room, comprising the steps of: (1) controlling a cancer therapy treatment system with a main controller, the main controller comprising hardware and software; (2) generating at least one image of the tumor using at least one imaging system controlled by the main controller; (3) using the at least one image and a software coded set of radiation treatment directives, the main controller auto-generating a radiation treatment plan; and (4) the main controller auto-delivering the positively charged particles, via a beam transport system and a nozzle system, from a synchrotron to the tumor according to the radiation treatment plan.

International Classification:

A61N 5/10

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.

International Classification:

A61N 5/10

Abstract:

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.
