DEVICE AND METHOD FOR TUNING A CHARGED PARTICLE BEAM POSITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024702 titled 'DEVICE AND METHOD FOR TUNING A CHARGED PARTICLE BEAM POSITION

Simplified Explanation

The patent application describes a particle therapy apparatus that is used to scan a charged particle beam over a target area for medical treatment. The apparatus is capable of scanning the beam over a larger surface area than the actual treatment surface. A beam stopper is placed downstream of the scanning magnets to prevent the beam from reaching certain areas while allowing it to reach the treatment surface. A control system is used to direct the beam to the beam stopper and measure its position, calculate the difference between the desired and measured positions, and then scan the beam over the target area based on this calculated difference.

  • The apparatus scans a charged particle beam over a target area for medical treatment.
  • It can scan the beam over a larger surface area than the treatment surface.
  • A beam stopper is used to prevent the beam from reaching certain areas while allowing it to reach the treatment surface.
  • A control system directs the beam to the beam stopper, measures its position, calculates the difference between the desired and measured positions, and scans the beam over the target area based on this difference.

Potential applications of this technology:

  • Particle therapy for cancer treatment: The apparatus can be used to precisely deliver a charged particle beam to a tumor, minimizing damage to surrounding healthy tissue.
  • Research and development: The apparatus can be used in research and development of particle therapy techniques and treatment planning algorithms.

Problems solved by this technology:

  • Precise targeting: The apparatus allows for precise scanning of the beam over the target area, ensuring accurate delivery of the treatment dose.
  • Minimizing damage to healthy tissue: By scanning the beam only over the treatment surface and preventing it from reaching other areas, the apparatus helps minimize damage to healthy tissue.

Benefits of this technology:

  • Improved treatment accuracy: The ability to measure and calculate the difference between the desired and measured positions of the beam allows for more accurate treatment delivery.
  • Reduced side effects: By minimizing damage to healthy tissue, the apparatus helps reduce side effects associated with particle therapy.
  • Increased treatment efficiency: The scanning capability of the apparatus allows for efficient delivery of the treatment dose over the target area.


Original Abstract Submitted

a particle therapy apparatus configured to scan a charged particle beam over a target according to a pre-defined treatment field which covers a treatment surface in an isocenter plane of the apparatus. the apparatus is capable of scanning the beam over a reachable surface which covers and is larger than the treatment surface. a beam stopper is arranged downstream of the scanning magnets of the apparatus, at a position to prevent the beam from reaching at least a portion of the reachable surface and to allow the beam to reach any portion of the treatment surface. a control system is configured to control the apparatus to direct the beam to the beam stopper and to meanwhile measure a position of the beam, to calculate a difference between a desired position and the measured position of the beam when directed to the beam stopper, and to scan the beam over the target according to the pre-defined treatment field by taking into account the calculated difference.
