Layout of the Francis H. Burr Proton Therapy Center treatment level showing the FDA approved radiation delivery system, which includes a cyclotron (upper left insert) and an array of over 50 magnets, each weighing between 1,000 and 5,000 pounds (highlighted in orange, blue and green). Protons can be delivered sequentially to any of the 3 treatment rooms by bending the beam using the magnets. Radiation is isolated to individual treatment rooms with 6 feet thick concrete walls.
Bill's tumor is sort of mushroom shaped. A die had to be cut the same size and shape as his tumor. The beam is directed through the die to the tumor.
We saw some of the die blanks and they look like brass, about the size of a dinner plate and a good two inches thick. I would love to find out how they machine them to match the tumors.
Libby says that today's session went very well.
