Gantry in Proton Therapy Unit (IMAGE)
Caption
Located inside the treatment room, a steel gantry can rotate around a patient to aim the proton beam at the correct angle to deliver treatment. Powerful magnets located outside the room guide the high-speed, high-energy protons into a beamline, an airless tube about as long as a football field. From the beamline, protons are channeled into the gantry.
