Transformative Proton Therapy. Superior Performance. Proven Results.


No other system can match the quality, size, cost and efficiency of the MEVION S250 Series™. The system has an elegant and streamlined footprint of less than 2,000 sq. ft per room, operates with up to 75% less 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 MEVION S250 Series operates similarly to conventional radiation devices, and is fully integrated with high precision patient positioning and imaging. A 6D robotic couch moves the target to its treatment position with submillimeter accuracy. The 2D/3D and 3D/3D radiographic imaging system is used to accurately confirm patient position and apply final alignment corrections. Once the patient is in position, the dedicated gantry-mounted proton accelerator provides on-demand beam delivery to the treatment site.



Our Solutions

The MEVION S250 Series is elegantly designed to deliver high-powered, efficient proton therapy treatments — optimizing both the outcomes and the economics of proton therapy. Built upon the world’s only gantry-mounted proton accelerator and benefitting from our patented direct beam technology, the MEVION S250 Series delivers on the therapeutic promise of proton therapy while enhancing beam quality, stability and uptime. The result is reduced system complexity, higher reliability and throughput, and lower capital and operating costs — making the MEVION S250 Series a compelling, financially viable solution for all cancer centers.


The MEVION S250, part of the successful MEVION S250 Series, offers next-generation volumetric delivery capabilities. By eliminating all the limitations and constraints associated with conventional beam transport lines and beam shaping systems, the MEVION S250 delivers a highly stable, uniform volumetric proton beam that is as simple to deliver as it is to validate.


The MEVION S250i with HYPERSCAN technology overcomes pencil beam scanning uncertainties through its unique and innovative design. With faster layer-switching time, smaller lateral penumbra, and invariant beam characteristics, a powerful Intensity Modulated Proton Therapy (IMPT) treatment is delivered at hyper-speed with a one liter target volume scanned in less than six seconds. This breakthrough technology makes the MEVION S250i ideal to deliver complex and robust IMPT dose distributions to targets close to critical structures or susceptible to movement.


MEVION S250mx™
The MEVION S250mx delivers fully scalable proton therapy centers with two, three or four room options. Each room is fully independent — providing inherent redundancy and guaranteeing 100 percent facility uptime, with beam availability 365 days a year. The MEVION S250mx safeguards and protects your financial outlays with lower initial cash flow demands, flexible installation and quicker clinical ramp-up.


The MEVION S250 Proton Therapy System is USFDA 510(k) cleared and complies with MDD/CE requirements.
HYPERSCAN has not been cleared by the USFDA for clinical use.
