Abstract
A system includes a patient support and an outer gantry on which an accelerator is mounted to enable the accelerator to move through a range of positions around a patient on the patient support. The accelerator is configured to produce a proton or ion beam having an energy level sufficient to reach a target in the patient. An inner gantry includes an aperture for directing the proton or ion beam towards the target.
Claims16
A system comprising:
- a patient support;
- an outer gantry on which an accelerator is mounted to enable the accelerator to move through a range of positions around a patient on the patient support;
- the accelerator being configured to produce a proton or ion beam having an energy level sufficient to reach a target in the patient;
- and
- an inner gantry comprising an applicator, the applicator comprising an aperture for directing the proton or ion beam towards the target, the inner gantry being configured to move the applicator through a range of positions around the patient and to position the proton or ion beam at a higher precision than a precision provided by movement of the outer gantry.
2 more elements
A system comprising:
- a patient support;
- a first gantry that is angularly movable relative to the patient support;
- a particle accelerator that is mounted on the first gantry, the particle accelerator being configured to provide a particle beam directly towards the patient support;
- and
- a second gantry positioned relative to the patient support, the second gantry being substantially C-shaped, the second gantry being configured to move an applicator comprising an aperture for directing the particle beam towards the patient support, the second gantry being configured to move the applicator through a range of positions around the patient and to position the proton or ion beam at a higher precision than a precision provided by movement of the first gantry.

A system comprising:
- a patient support;
- a first gantry that is angularly movable around to the patient support;
- a particle accelerator that is mounted on the first gantry, the particle accelerator being configured to provide a particle beam directly towards the patient support, the particle accelerator being movable around the patient support on the first gantry;
- and
- a second gantry positioned relative to the patient support and inside of a volume traversed by movement of the first gantry and particle accelerator, the second gantry being substantially C-shaped such that at least part of the inner gantry is below the patient support and at least part of the inner gantry is above the patient support.
