MEVION S250-FIT™ 

 

Bringing Proton Therapy Closer to Patients.

​

Key Features & Advantages

​

Targeted Dose — Healthy Tissue Protection

• Through the physical properties of protons and the Bragg peak, radiation can be concentrated at the intended depth, with minimal dose beyond the target.

• The ability to limit radiation exposure to surrounding healthy tissue is particularly important when a tumor is located near sensitive organs. The potential benefit is assessed individually through treatment planning.

Advanced Beam Shaping

• HYPERSCAN® Pencil Beam Scanning supports Intensity Modulated Proton Therapy (IMPT), tailoring the dose distribution to the shape and depth of the target.

• The Adaptive Aperture® proton multileaf collimator (pMLC) helps precisely shape the beam, supporting a sharp dose falloff at the treatment area's boundaries.

​

Upright Positioning — A Different Treatment Experience

• Leo Cancer Care’s Marie® system supports upright patient positioning and controlled 360-degree patient rotation, allowing the fixed beam to approach the target from different angles.

• This architecture eliminates the need for a large rotating gantry and offers a different approach to patient positioning and the treatment experience.

Imaging in the Treatment Position

• Integrated CT enables three-dimensional imaging of the patient in the upright treatment position.

• The combination of imaging, positioning and treatment planning with RayStation® from RaySearch Laboratories creates an integrated platform for the clinical delivery of upright proton therapy.

Compact Design — New Installation Possibilities

• The S250-FIT is designed for installation within an existing linear accelerator vault, subject to an assessment of its dimensions, shielding and technical infrastructure.

• Using existing space can reduce the construction requirements and complexity of establishing a proton therapy unit. The first installation at Stanford Medicine was completed within an existing radiation therapy vault, without constructing a new building.
