The MEVION S250 Series™ has an elegant and streamlined footprint of less than 2,000 sq. ft per room, operates with up to 75% fewer staff members, uses up to 90% less energy, has capital costs that are 80% lower than traditional systems and can ramp up to full capacity in as little as three months. The advantage of proton therapy comes from a phenomenon known as the Bragg Peak. Unlike photons, protons can be charged to reach the exact depth where a tumor is located, then stop. Very little proton radiation continues past the tumor site.
