RaySearch Laboratories AB (publ) announces an important clinical milestone at Advanced Radiation Therapeutics (ART), a new radiation oncology clinic in San Luis Obispo, California, USA, where patients are now being treated using RayStation®* and RayCare®*. Clinical treatments began in mid-August 2026 on a Varian TrueBeam®** linear accelerator, the most common radiation treatment machine in the world.
ART selected RayCare® and RayStation® in 2025 for its new state-of-the-art radiation therapy center, established through a partnership between AKSM/Oncology and Urology Associates of The Central Coast. The center is part of AKSM/Oncology’s long-standing network of freestanding radiation therapy centers across the USA. It combines RaySearch’s oncology information system and treatment planning system with the Varian TrueBeam machine, supporting coordinated workflows from treatment planning through treatment delivery.
RayCare supports key oncology workflows, including treatment management, scheduling and care coordination. Together with RayStation, it enables seamless information flow across the radiation therapy process and interoperability with TrueBeam. The clinic has now completed its implementation and is fully operational with the integrated RayCare, RayStation and TrueBeam solution, establishing ART as a USA reference site.
The interoperability between RayCare and TrueBeam was established in 2023. In 2024, Iridium Network in Belgium became the first cancer center globally to treat patients using RayCare in combination with TrueBeam.
“Treating our first patient with RayCare and TrueBeam marks an important milestone for our team and the culmination of extensive work by our physicians, physicists, dosimetrists, therapists and the RaySearch implementation team. The integrated RayCare, RayStation and TrueBeam solution provides a modern platform that supports streamlined workflows and the advanced radiation therapy techniques we aim to offer patients across California’s Central Coast,” says Paul Pagnini, MD, radiation oncologist at Advanced Radiation Therapeutics.
“The clinical launch of RayCare at ART is another example of the continued progress we are seeing as more clinics select and implement RayCare. TrueBeam is dominant in the USA, our largest market, and our interoperability with it opens up significant opportunities to bring RayCare to clinics that can build on their existing treatment delivery infrastructure,” says Johan Löf, founder and CEO of RaySearch Laboratories.
