Leo Cancer Care Introduces Grace™, the First Upright Photon Therapy System, at ASTRO 2025

MIDDLETON, Wis., Sept. 28, 2025 /PRNewswire/ -- Leo Cancer Care is using ASTRO 2025 to launch Grace™, the company's upright photon therapy system. Grace is named after American computer scientist and U.S. Navy Rear Admiral Grace Hopper, who famously said, "The most dangerous phrase in language is 'But we've always done it this way.'" The name reflects Leo Cancer Care's mission to challenge the conventions of radiation therapy.

Grace will deliver conventional x-ray radiation therapy with patients positioned upright, a natural posture that growing global research indicates may support more consistent anatomical positioning and organ stability compared with conventional supine treatments. Patients who have experienced the technology report that the upright approach also creates a more connected and comfortable experience.

Stephen Towe, Co-Founder and CEO of Leo Cancer Care commented: "Leo Cancer Care is already known for delivering upright particle therapy technology, and over the past few years we have seen a real paradigm shift as a result. Grace represents a return to our original company focus of delivering more cost-effective photon treatments to a global stage without sacrificing on treatment quality. Our technology has always been bold, but we are pioneering with purpose and that purpose is to put the patient truly back at the center of their treatments."

The system will integrate a fan beam CT scanner at the treatment isocenter, enabling planning-quality imaging throughout the treatment workflow, paving the way for online adaptive radiotherapy in the future. The solution also features a large, ultra-fast multi-leaf collimator, challenging conventional MLC speeds currently on the market.

Grace will also be compatible with RaySearch Laboratories' RayStation®, the first treatment planning system to incorporate support for upright radiation therapy, as well as RayCare®, the next-generation oncology information system.  

Utilizing a fixed radiation beam, the solution will reduce primary shielding requirements and lower infrastructure costs, helping to expand access to radiation therapy worldwide. Leo Cancer Care believes that the combination of upright positioning, integrated CT imaging, and high-efficiency delivery will set Grace apart from traditional linacs.

The first five pre-commercial Grace systems will be installed at leading healthcare institutions as part of the Upright Photon Alliance, a global research collaboration formed in October 2024. Alliance members include Centre Léon Bérard, Cone Health, IHH Healthcare, Mayo Clinic and OncoRay, who will investigate Grace's potential to improve patient outcomes and challenge conventional radiotherapy practices.

Leo Cancer Care continues to innovate in radiation therapy, developing technologies that challenge decades of convention while making advanced cancer treatment more human and accessible for patients worldwide.

Please note: Leo Cancer Care's Grace solution is under development and is not cleared or approved for sale. It is presented for research and discussion purposes only.
