Abstract

An integrated beam modifying assembly for use with a proton beam therapy machine. Typically the snouts of a proton beam therapy machine are adapted to receive separate apertures and range compensators. Applicants provide an integrated assembly for slotting into the snout of a proton beam therapy machine, which integrated assembly incorporates both aperture material and range compensator material for profiling, shaping, and modulating the beam.

Claims

1. For use with a PBT machine, the PBT machine having a gantry and a snout and a proton beam emitter for emitting a proton beam, the gantry for engaging the snout, the snout having an inner diameter and one or more slots, the one or more slots having slot walls and having indexing means thereon, the slots having a perimeter, a system for modifying the proton beam, the system comprising:

an integrated assembly adapted to have an aperture material portion and a range compensator material portion, the two materials of different compositions.

2. The system of claim 1, wherein the integrated assembly includes exterior walls adapted to engage the slot walls.

3. The system of claim 1, further including a frame, the frame adapted to engage the slot walls and the integrated assembly.

4. The system of claim 1, wherein the portion of the integrated assembly includes a cavity having outer walls greater than the snout inner diameter and inner walls defining the aperture opening.

5. The system of claim 4, wherein the cavity is substantially upstream of a modulation profile of the range compensator material.

6. The system of claim 4, wherein the cavity is substantially downstream of a modulation profile of the range compensator material.

7. The system of claim 4, wherein the integrated assembly includes exterior walls adapted to engage the slot walls.

8. The system of claim 4, further including a frame, the frame adapted to engage the slot walls and the integrated assembly.
