Abstract
Systems and techniques may be used for radiotherapy. An example system may include a fixation device arranged to receive and immobilize a patient. The example system may include a first filter arranged to extend along a first portion (e.g., a spine or cranium) of the patient, the first filter attached to the fixation device at a first location, the first filter including a plurality of beam attenuating elements. The example system may include a fixed beam proton delivery system arranged to deliver a therapeutic proton radiation dose attenuated via the first filter to the first portion of the patient.
Claims16
A system for radiotherapy comprising:
- a fixation device arranged to receive and immobilize a patient;
- a first filter arranged to extend along a first portion of the patient, the first filter attached to the fixation device via one or more supports, the first filter including a plurality of beam attenuating elements;
- a particle treatment system, including an ion source and a plurality of magnets, the particle treatment system arranged to deliver a therapeutic particle radiation dose attenuated via the first filter to the first portion of the patient, wherein the first filter is attached to the fixation device at a first location;
- and
- a second filter arranged along a posterior oblique of the patient, the second filter attached to the fixation device at a second location, wherein the particle treatment system is further arranged to deliver a therapeutic proton radiation dose attenuated via the second filter to a second portion of the patient, and wherein the therapeutic proton radiation dose attenuated via the second filter is delivered to the second portion of the patient from a vertical beamline, and the therapeutic proton radiation dose attenuated via the first filter is delivered to the first portion along a different beamline than the vertical beamline.
A method comprising:
- receiving a volumetric image of a patient in a single scan;
- arranging a first filter to extend along a first portion of the patient, the first filter attached to a fixation device via one or more supports at a first location;
- arranging a second filter along a posterior oblique of the patient, the second filter attached to the fixation device at a second location;
- registering an image of the patient captured in situ to the volumetric image, the captured image including the patient, the first filter, and the second filter;
- identifying a treatment position of the patient from a registration;
- delivering, from a particle treatment system including an ion source and a plurality of magnets, a field of particle radiation therapy to the first portion of the patient attenuated via the first filter, based on the identified treatment position;
- and
- delivering, using the particle treatment system, a therapeutic proton radiation dose attenuated via the second filter to a second portion of the patient from a vertical beamline, and wherein the therapeutic proton radiation dose attenuated via the first filter is delivered to the first portion along a different beamline than the vertical beamline.
