Mevion S250-FIT
Family: Mevion S250 · Modality: Proton Therapy
Mevion's current-generation single-room compact proton-therapy system — extends the S250 architecture with HYPERSCAN pencil-beam scanning and modern image-guidance. Delivers proton therapy at community-hospital scale via gantry-mounted superconducting synchrocyclotron, eliminating the multi-room footprint of conventional proton centers.
Distinctive technology
- HYPERSCAN pencil-beam scanning — modulated-spot delivery with rapid energy switching; the modern PBS standard on the compact platform.
- Adaptive Aperture — collimating element on configured units.
- Gantry-mounted synchrocyclotron — single-room footprint architectural distinction from multi-room IBA Proteus PLUS / Hitachi PROBEAT-V.
- Image-guided proton therapy — kV CBCT and stereoscopic-X-ray patient-positioning verification.
- Modern motion-management — gating / breath-hold integration.
Variants in family
- Mevion S250 — original 2013-era platform.
- Mevion S250i — refresh generation.
- Mevion S250-FIT (this card) — current with HYPERSCAN PBS.
Clinical use
- Pediatric oncology, base-of-skull, CNS, re-irradiation, eye / orbit, AYA cancers — same indications as multi-room proton centers, delivered at community-hospital scale.
Refurb posture
- No meaningful refurb market — installed base small, per-vendor, and program-level.
- Service-contract continuity dominates operating economics.
- Pre-HYPERSCAN S250 / S250i legacy installs face evolving service-support timelines.
