Rob getting setup as seen in one of the monitors that are used to watch the proton radiation procedure by the doctors, assistants, physicists and visitors to the TRIUMF center.

It’s much harder than it looks…. Christine (from the BC Cancer Agency) Has to make sure that I’m correctly positioned while in the chair. Measurements are to the 1/1000 of a milimeter, that’s how exact the proton radiation is directed at the tumor behind my left eye.

Once the mask is made they have to put it to use. They use it by fitting it on your face having you clamp down on a molded bite plate and there you are, anchored in place. The chair is a technological marvel, as detailed elsewhere.
