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.

Claims

1. 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 aperture for directing the proton or ion beam towards the target.
