Problem
Conventional radiotherapy relies on massive rotating gantries that require patients to lie supine, leading to high capital costs, limited treatment room flexibility, and potential patient discomfort or increased internal organ motion during treatment.
Solution
Leo Cancer Care offers an upright radiotherapy platform that rotates the patient instead of the heavy gantry. By integrating an upright patient positioning system with a fan‑beam CT scanner at the isocenter, the solution enables simulation, daily imaging, and treatment within a single compact room. The upright orientation reduces internal organ motion, improves anatomical consistency, and enhances patient comfort and sense of control. The system is compatible with any fixed radiation beam, allowing delivery of photon, proton, carbon‑ion, and BNCT therapies without the need for large, expensive gantry installations. This approach lowers capital expenditure, streamlines workflow, and expands access to advanced radiotherapy modalities.
Target Audience
Primary customers are radiation oncology centers, proton therapy facilities, and academic cancer institutes seeking to modernize their treatment rooms while reducing capital costs and improving patient experience.
Features
- Upright patient positioning system that rotates the lightweight patient rather than a 100‑ton gantry
- Integrated fan‑beam CT scanner positioned at isocenter for on‑site simulation and daily adaptive imaging
- Compatibility with fixed radiation beams, supporting photon, proton, carbon‑ion, and BNCT treatments
- Compact room footprint that combines simulation and treatment, reducing facility construction costs
- Improved organ stability and reduced motion for head‑&‑neck, lung, breast, and liver cancers, enhancing treatment accuracy
- Patient‑centered design that increases comfort and perceived control during therapy
