Closer to Care
A New Way of Thinking About Particle Therapy
For decades, cancer treatment has been built around machines. Marie® represents a shift, rethinking particle therapy around people, not the machine, so advanced care can reach more patients in more places.
Particle therapy should not feel out of reach clinically, geographically, or emotionally. Closer to Care is about reducing the distance to cancer treatment by rethinking how particle therapy is designed and delivered. By utilizing a fixed beam and slowly rotating the patient, Marie® opens the door to wider access, a more human treatment experience, and new possibilities for care delivery.

Bringing Care Closer—In Three Critical Ways
Closer to Access
Expanding who can offer particle therapy
Marie® is designed to reduce traditional barriers such as size, complexity, and infrastructure so more centers can offer particle therapy. By enabling treatment in more locations, closer to where patients live, care becomes physically accessible to more people. View the Case Study
Closer to Experience
A more natural, more empowering way to treat patients
Upright patient positioning and eye‑level clinician interaction, transform the experience from something patients endure, to something designed around dignity, comfort, and human connection.
Closer to Precision Care
Enabling future‑ready precision through flexibility
Marie® supports a precision‑care mindset, adapting to patients, workflows, and evolving clinical approaches, rather than constraining them.
Meet Marie®—Designed Around the Human
Marie is the result of rethinking particle therapy. By fixing the beam and designing around the human body, Leo Cancer Care created a system that is smaller, more adaptable, and fundamentally more human.
Enabling cancer care teams to focus on what matters most: the patient.
Hear from our CEO, Stephen Towe, about how Marie is making proton therapy more accessible than ever before.
Thought Leadership
Leading the Conversation on Access to Particle Therapy
Clinical Benefits
- Enables upright positioning that reflects natural anatomy and supports anatomical stability
- Promotes eye‑level, human interaction between patients and care teams
- Adapts to patient variability rather than constraining patients to rigid treatment positions
- Supports reproducibility and precision across treatment sessions
System Benefits
- Compact, gantry‑less design reduces infrastructure complexity and footprint
- Integrates flexibly into existing facilities and diverse care environments
- Creates a pathway to expand access to particle therapy beyond traditional centers
- Beam‑agnostic, future‑ready platform aligned with adaptive, decentralized care models
Clinical + System Benefits
Designed for Clinical Reality and Impact
Marie® represents more than a new way to deliver treatment rethinking how radiation therapy is designed, experienced, and scaled. By aligning with human physiology and emerging care models, Marie® enables clinicians to deliver particle therapy while helping health systems overcome the structural and economic constraints of legacy infrastructure.

What our Partners Say
McLaren will realize a sizeable capital cost reduction by implementing the Leo Cancer Care upright positioning system, instead of our present 3-story, +100 ton, rotating gantry solution
Daniel Medrano, McLaren Proton Therapy Center
What our Partners Say
This new approach has the potential to make proton treatment more effective, more accessible and much more patient-friendly. We are excited to be leading the way on this concept that could become a model for other health systems around the country.
Dr Paul Harari, UW Health
What our partners say
It’s challenging, but exciting, to be the first centre in the world to contribute to the validation of a new paradigm in radiotherapy treatment.
Professor Vincent Gregoire, Centre Léon Bérard
