Gantries - Instruments of Precision

Three of the four treatment rooms use gantries to deliver the proton beam. The 90-ton, three-story gantries can be rotated 360 degrees to deliver the beam at the precise angle prescribed by the physician. Most of the gantry is concealed by the walls and floor of the treatment room, and the patient, lying within the gantry, only sees the front of the proton nozzle rotating prior to treatment. Each treatment takes about 15 minutes for alignment and treatment time, and the patient feels nothing.
