Marie represents a paradigm shift in the delivery of particle therapy, combining an upright patient positioning system and a CT scanner that reimagines the treatment experience for both patients and clinicians, whilst drastically reducing the size and cost compared to existing particle therapy solutions.

“This clearance marks a major milestone not just for Leo Cancer Care, but for the future of cancer treatment,” said Stephen Towe, CEO of Leo Cancer Care. “We’ve long believed there’s a better, more human way to deliver radiotherapy. One that puts the patient at the heart of the treatment experience and embraces smarter, more compassionate design. Marie is the embodiment of that belief.”

Particle therapies such as proton and carbon ion therapy have long been considered the gold standard in radiation oncology. However, the cost, size, and complexity of conventional systems with large rotating gantries have historically limited widespread adoption.
