Leo Cancer Care Shifts Radiotherapy from Lying Down to Upright

Patients can now receive cancer treatment in an upright position following the first clinical use of Leo Cancer Care’s Marie system. By rotating the patient around a fixed radiation beam rather than moving heavy machinery, the platform offers a departure from traditional radiotherapy, aiming to increase comfort and accessibility.

The platform, which recently reached clinical reality in June 2026, is beam-agnostic, meaning it integrates with both photon and proton fixed-beam technologies. This flexibility allows health networks to build systems without being locked into a single manufacturer. Developed in partnership with Mevion Medical System and powered by RaySearch Laboratories' RayStation, the setup enables clinicians to perform imaging, planning, and treatment using a single reference point.

Beyond technical integration, the system is designed to improve the patient experience. Many individuals struggle to lie flat due to pain, anxiety, or respiratory issues; the upright orientation provides a more natural posture and allows for direct eye contact with the clinical team. CEO Stephen Towe stated that this milestone proves the technology is no longer a concept but a functional tool. Research suggests this method may also improve anatomical consistency and reduce organ motion. Looking ahead, the company is developing a dedicated fixed-beam photon platform to further streamline how radiotherapy is delivered globally.
