1. A system comprising:
- a patient support;
an outer gantry comprising legs between which a particle accelerator is mounted to enable the particle accelerator to move through a range of positions around a patient on the patient support, the particle accelerator being configured to produce a proton or ion beam having an energy level sufficient to reach a target in the patient; and
a robotic arm that is between the legs of the outer gantry and that is between the particle accelerator and the patient, the robotic arm being configured to hold an aperture and to position the aperture between the particle accelerator and the patient in order to direct the proton or ion beam to the patient, the robotic arm being configured to move the aperture in three dimensions relative to the patient.

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 a robotic arm capable of directing an aperture for directing the proton or ion beam towards the target.

18. A system comprising:
-
a gantry comprising legs between which a particle beam accelerator is mounted, the legs being movable to move the particle beam accelerator to positions above and below a target, the particle beam accelerator for directing a particle beam towards the target; an aperture located between the particle beam accelerator and the target, the aperture for modifying the particle beam; and a robotic arm that is between the legs of the gantry and between the particle beam accelerator and the target, the robotic arm for holding the aperture, the robotic arm being movable relative to the target; wherein the robotic arm is computer controlled to move the aperture in three dimensions relative to the target in order to position the aperture. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
