A RADIATION MODULATOR ASSEMBLY AND RADIATION DELIVERY APPARATUS FOR USE IN ION-BASED RADIOTHERAPY AND A PLANNING METHOD FOR ION-BASED RADIOTHERAPY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033540 titled 'A RADIATION MODULATOR ASSEMBLY AND RADIATION DELIVERY APPARATUS FOR USE IN ION-BASED RADIOTHERAPY AND A PLANNING METHOD FOR ION-BASED RADIOTHERAPY

Simplified Explanation

The patent application describes a radiation delivery system for radiotherapy treatment. The system includes a chair for the patient and a modulating assembly. The modulating assembly consists of a modulator wheel, which is shaped as a rim defining the circumference of a circle or an elliptic shape. The modulator wheel has varying thickness around its circumference. The wheel is positioned in a way that a beam from a radiation source to the patient intersects the rim of the modulator wheel. The wheel rotates, causing the beam to intersect the rim at different positions around the circumference. As the beam passes through the varying thickness of the wheel, the energy of the beam is modulated.

  • The radiation delivery system includes a chair for the patient and a modulating assembly.
  • The modulating assembly consists of a modulator wheel shaped as a rim.
  • The modulator wheel has varying thickness around its circumference.
  • The wheel is positioned to intersect the beam from the radiation source to the patient.
  • The wheel rotates, causing the beam to intersect the rim at different positions.
  • The varying thickness of the wheel modulates the energy of the beam.

Potential applications of this technology:

  • Radiotherapy treatment for cancer patients.
  • Precision delivery of radiation therapy.
  • Modulation of radiation energy for targeted treatment.

Problems solved by this technology:

  • Allows for precise modulation of radiation energy.
  • Enables targeted treatment by varying the energy of the beam.
  • Provides a mechanism for controlling the dosage and distribution of radiation.

Benefits of this technology:

  • Enhanced precision in radiation therapy.
  • Improved targeting of cancer cells while minimizing damage to healthy tissue.
  • Increased control over the dosage and distribution of radiation.
  • Potential for more effective and efficient treatment.


Original Abstract Submitted

a radiation delivery system includes a chair on which the patient may be seated during treatment and a modulating assembly () for use in radiotherapy comprises a modulator wheel (), said modulator wheel being shaped as a rim defining the circumference of a circle or an elliptic shape, and having varying thickness around the circumference, said modulator wheel () being arranged in such a way that a beam traveling from a radiation source () to a patient will intersect the rim of the modulator wheel, said wheel being arranged to rotate in such a way that the beam will intersect the rim in varying positions around the circumference. the wheel will modulate the energy of the beams passing through material having varying thickness as the modulator wheel rotates.
