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.
Claims20
A system comprising:
- a patient support to support a patient;
- a synchrocyclotron to produce a proton or ion beam having an energy level sufficient to reach a target in the patient on the patient support;
- an outer gantry on which the synchrocyclotron is mounted to enable the synchrocyclotron to move through a range of positions around the patient on the patient support;
- and
- an inner gantry comprising a beam-focusing device to shape the proton or ion beam before the target;
- wherein the synchrocyclotron (i) comprises a magnet that produces a magnetic field strength of up to 20 Tesla, (ii) is configured to produce, for delivery to a patient, a beam of charged particles having an energy level of at least 150 MeV, and (iii) has a weight less than 30 Tons.

A system comprising:
- a patient support to support a patient;
- a particle accelerator to produce a proton or ion beam having an energy level sufficient to reach a target in the patient on the patient support;
- an outer gantry on which the particle accelerator is mounted to enable the particle accelerator to move through a range of positions around the patient on the patient support;
- and
- an inner gantry that is C-shaped and that comprises a beam-focusing device, the beam-focusing device being movable along the inner gantry and being configured to collimate the proton or ion beam before the target;
- wherein the particle accelerator (i) comprises a magnet that produces a magnetic field strength of up to 20 Tesla, (ii) is configured to produce, for delivery to a patient, a beam of charged particles having an energy level of at least 150 MeV, and (iii) has a weight less than 30 Tons.
