PBS employs a highly focused proton beam that is directed at the tumor. The beam is controlled by powerful magnets that adjust its direction and intensity. The process involves delivering the proton beam to a specific depth and spreading it out to cover the tumor in a meticulous manner. By adjusting the energy of the protons, PBS can target tumors at various depths within the body, ensuring that the highest dose is delivered to the tumor with minimal exposure to surrounding healthy tissues.
