Grace: Redefining Radiotherapy Delivery

The Grace system is a revolutionary radiotherapy device engineered to deliver conventional X-ray radiation treatment with unparalleled precision and patient comfort. Unlike traditional linear accelerators (linacs) where patients lie supine, Grace utilizes an upright patient positioning system that offers six degrees of freedom and 360° continuous rotation. This system positions the patient in front of a stationary 6 MV photon linear accelerator, eliminating the need for a bulky, rotating gantry.

Key features of the Grace system include an integrated fan-beam CT scanner at the treatment isocenter, allowing for planning-quality imaging throughout the entire treatment workflow. This capability paves the way for online adaptive radiotherapy, where treatment plans can be dynamically adjusted based on real-time patient anatomy. Furthermore, Grace incorporates an ultrafast multileaf collimator (MLC), designed to optimize dose conformity and treatment efficiency, potentially challenging the speeds of conventional MLCs currently on the market. The system is also designed for compatibility with RaySearch Laboratories’ (STO: RAYB) RayStation® treatment planning system and RayCare® oncology information system.

The development of Grace follows Leo Cancer Care's earlier success with its Marie™ upright particle (proton) therapy solution, which received FDA 510(k) clearance for its patient positioning system in May 2025. The company’s commitment to "pioneering with purpose" is evident in Grace, named after American computer scientist and U.S. Navy Rear Admiral Grace Hopper, whose famous quote, "The most dangerous phrase in language is 'But we've always done it this way'," encapsulates Leo Cancer Care's mission. While Grace is currently under development and not yet commercially available, its formal launch at ASTRO 2025 and the formation of the Upright Photon Alliance signal a strong trajectory towards market entry. The alliance, comprising leading institutions like Centre Léon Bérard, Cone Health, IHH Healthcare (KLSE: IHH, SGX: Q0F), Mayo Clinic, and OncoRay, will facilitate the installation of the first five pre-commercial Grace systems, gathering crucial research data.
