Kansas City
Proton Institute

The centerpiece of the new Kansas City Proton Institute is a MEVION S250iTM Proton Therapy System with HYPERSCAN® Pencil Beam Scanning accelerator.

The Proton Therapy System is secured inside a three-story high, 42-foot- by-47-foot “vault” treatment room featuring concrete walls ranging from three to seven and a half feet thick located adjacent to the new 40,000-square-foot, two-story Medical Office Building for Kansas City Urology Care. Because being as little as one inch off in thickness would result in less radiation shielding, the center was designed and built with extreme precision, with tolerances less than three-quarters-inch wall-to- wall and one-inch floor-to-ceiling.

The world’s only gantry-mounted proton accelerator, the MEVION S250i, features the HYPERSCAN® pencil beam scanning technology and Adaptive Aperture® pMLC that delivers a highly stable, fast, precise and uniform proton therapy beam. The complete unit includes the 30,000-pound accelerator and 72,000 pounds of arms and counterweights.

Currently, there are only 42 proton centers in the United States. Proton therapy, which has fewer side effects than traditional cancer treatments and can be used for many types of cancer, uses high-energy beams of protons to precisely deliver radiation to a tumor, reducing or eliminating unwanted radiation exposure to surrounding, healthy tissue.
