September 23, 2016 — Mevion Medical Systems announced that it will be installing its Mevion S250i proton therapy system at the Zuidoost Nederland Protonen Therapie Centrum, BV (ZON-PTC) in the Netherlands. The system delivers high-quality adaptive intensity modulated proton therapy (IMPT) with Mevion’s Hyperscan pencil beam scanning and Adaptive Aperture technology.
Located on the Brightlands Maastricht Health Campus, ZON-PTC will, for the first time, make proton therapy available to patients in the southeast region of the Netherlands. Construction of the ZON-PTC facility will begin this year and the first cancer patients will be treated in 2018. The center will be affiliated with MAASTRO clinic and Maastricht University Medical Center, with the aim of treating 400 cancer patients per year. Mevion was selected as the preferred vendor after a stringent tender process.
“Mevion’s compact proton therapy system will give us the ability to treat patients with the latest IMPT technology, including unparalleled treatment speed to minimize motion uncertainties and the sharpest penumbra, without the need for manual apertures and adjustments, while still being the most cost-effective proton solution,” said Geert Bosmans, project director and medical physicist of ZON-PTC. “Additionally, the system will have state-of-the-art 3-D radiographic imaging to position the patient, and Mevion’s solutions offer the possibility, if needed, to expand easily in the future.”
Maria Jacobs, CEO of ZON-PTC and MAASTRO clinic said, “Thanks to Mevion’s small footprint, we can simply install the Mevion system in the space of one and a half existing conventional radiation bunkers. Mevion’s proven clinical results, small size and cost-effectiveness make it the gold standard for proton therapy systems.”
The Mevion S250i Proton Therapy System with Hyperscan pencil beam scanning technology can volumetrically scan a typical lung tumor in less than two seconds – eliminating many of the challenges that slower pencil beam scanning solutions encounter. Additionally, the Adaptive Aperture technology includes a low-profile micro-multileaf collimator (mMLC) system designed specifically for pencil beam scanning that is capable of delivering the sharpest penumbra physically achievable with protons without the need for manual apertures and adjustments.
