As I have mentioned previously they take 2 week to formulate the plan before they start treatment. We found out a few more details and saw the proton treatment rooms for the first time
They have to manufacture 2 other bits for the beam machine as well as the mask
One a brass beam size aperture and a plastic lens which allows different strengths of beam through
These pics are an example of the dies used

| Customized dose-shaping devices used for proton beam therapy. A brass aperture shaped to the outline of a target blocks the proton beam outside a specified safety margin. The penetration depth of the protons that pass through the aperture opening is adjusted to match the shape of the target with a Lucite range compensator. A target is depicted in red in the rightmost figure with the proton radiation dose conforming to its shape and avoiding a critical structure shown in green |
