Transforming Proton Therapy For Good

MEVION S250-FIT: Proton Therapy That FITs Inside A LINAC Vault

Leo Cancer Care and Mevion Medical Systems partnered in 2022 to develop ultra-compact, upright proton therapy systems. The MEVION S250-FIT combines Mevion’s world’s smallest proton accelerator with Leo Cancer Care’s Marie™ upright patient positioning and CT imaging system, positioned in front of a fixed beam line.

This collaboration aims to make proton therapy more accessible and affordable, particularly for facilities with limited space.

Please note: Not yet available for clinical use.

Features and Benefits

Complete 360-degree Beam Access Proton Therapy Now FITs in a LINAC Vault

HYPERSCAN Pencil Beam Scanning

Next-generation pencil beam scanning system delivering sharp, fast, and robust IMPT treatments. Featuring hyper-fast layer switching, optimized spot size, and Adaptive Aperture® proton MLC (pMLC), powered by RayStation.
Online Adaptive

With a diagnostic-quality upright fan beam CT at isocenter, the S250-FIT enables daily imaging and online adaptation, allowing real-time plan adjustments to match patient anatomy.
SmartARC™ Delivery

The MEVION S250-FIT powers SmartARC — an advanced arc-based technique that delivers VMAT-like speed and efficiency in proton therapy with conformal dose coverage with faster and simplified workflows.
Patient & Clinician Experience

Positioning a patient eye to eye with the team treating them allows both patient and therapist to read each others body language to interpret subtle distress or pain cues. It also allows a connection to be made which is the foundation for 
a trusting relationship in a time when patients feel vulnerable.

FAQs

Questions are the start of change

Removing the need for a gantry means existing treatment rooms, even linac vaults, can be given a new lease of life, without the need for new costly construction or hospital developments. Our solution Marie, is beam agnostic, meaning it can be placed in front of any fixed beam. Our existing partnership with Mevion Medical Systems provides a compact proton therapy solution that can fit inside a LINAC vault.

Our solution is approximately two-thirds smaller than conventional supine technology, making this previously considered, costly modality now a commercially viable option.
