Proton Therapy

Hyperscan and Adaptive Aperture

The MEVION S250i™ with HYPERSCAN™ pencil beam scanning technology delivers high-quality, robust Intensity Modulated Proton Therapy (IMPT) treatments at hyper-speed and without compromise. Featuring Mevion’s Adaptive Aperture™, HYPERSCAN delivers high quality, robust pencil beam scanning for IMPT. Adaptive Aperture can automatically tailor beam characteristics to match at tumor at any spot and depth. The benefits are a sharper penumbra that eliminates dose uncertainty and delivers less radiation to healthy tissues. It is ideal for treating shallow pediatric or brain tumors, where small spot sizes are difficult to achieve. The Adaptive Aperture is a ground breaking low profile Multileaf Collimator (MLC) system specifically designed for pencil beam scanning. The system uses a fully automated adaptive aperture that generates layer-by-layer specific beam collimation and blocking identical to conventional proton therapy apertures.

Proton Therapy System

The MEVION S250™ provides next-generation proton therapy. Built on the world’s only gantry-mounted proton accelerator, the MEVION S250 delivers a highly stable, uniform proton beam that is simple to deliver. The MEVION S250 has been treating patients since 2013 at multiple treatment sites across the US. This 3D cutaway shows how the MEVION S250 Series’ 190 degree rotating gantry, with the world’s only gantry mounted proton accelerator, rotates around the patient to allow for precise treatment from every angle with complete four pi (4π) beam access.
