Regarding the CE Mark for the MEVION S250i Proton Therapy System, Perjan Pleunis, Field VP of Business Development (EMEA) notes, “This milestone is part of Mevion’s global expansion of cutting-edge compact proton therapy systems in Europe.”  He adds, “Mevion has led the way in establishing compact proton therapy as the most technologically advanced and financially viable choice in proton therapy.” European CE Marking is the first regulatory clearance for the MEVION S250i system. Mevion also submitted for US FDA 510(k) clearance in September.

First European Installation
The first European MEVION S250i proton therapy system installation will be completed in 2018 at the Zuid-Oost Nederland Protonen Therapie Centrum (ZON PTC) at the Maastro Clinic in Maastricht, the Netherlands.

The MEVION S250i system will be the first of its kind in Europe. Designed to deliver faster, sharper, and more robust treatments, the HYPERSCAN PBS technology incorporates the fastest energy layer switching, optimized spot sizes, and the Adaptive Aperture™ proton multi-leaf collimator system. This capability provides dose gradient advantages with up to a three times sharper lateral penumbra reducing dose uncertainty at the edge of the tumor thus sparing healthy tissue and preventing unnecessary radiation to sensitive locations. This improved precision in delivery is combined with hyper-fast beam delivery reducing the sensitivity to motion that current PBS technologies face when treating moving lesions such as those in the thoracic cavity.

Built on Leading Compact Proton Therapy Technology
The MEVION S250i system is based on Mevion’s high efficiency, low financial risk S250 Series platform. The core technology of the S250 Series includes the world’s only gantry mounted superconducting synchrocyclotron, a six degree-of-freedom treatment couch and advanced in-room IGRT imaging, all leveraged in the S250i system. This compact, fully integrated platform has years of successful clinical experience, proven financial viability and now delivers next generation pencil beam scanning.

The MEVION S250i lowers the cost per patient by reducing capital costs, reducing operating costs, and increasing treatment throughput. Mevion customers have achieved the fastest per-room patient ramp-up in the history of proton therapy. High throughput is achieved via linac-like workflow, low maintenance requirements, and industry-leading uptime. Demonstrating that compact proton therapy is a viable option for any size cancer center is core to Mevion’s mission of making proton therapy accessible to as many patients as possible.
