June 19, 2024 — RaySearch Laboratories AB announced a milestone in radiotherapy technology where RaySearch’s RayStation was used for the world’s first clinical treatment using OXRAY, a new treatment machine from Hitachi. The event took place on June 17 at Narita Memorial Hospital in Toyohashi, Japan.
OXRAY represents a pioneering radiotherapy system featuring a Gimbal-mounted beam delivery system. RayStation was used to drive its motion tracking functionality, dual-source CBCT image-guided radiotherapy for precise patient positioning, and dynamic swing arc capabilities. Developed in collaboration with Kyoto University Hospital, the OXRAY system has been seamlessly integrated into RayStation through close collaboration between RaySearch and Hitachi.
By joining the innovative capabilities of OXRAY with RayStation's sophisticated planning software, clinicians can achieve unprecedented precision and flexibility in radiation therapy, ensuring optimal patient outcomes.
Dr. Yuta Shibamoto, MD of the Meiyo-kai Narita Memorial Hospital group says: “There are so many different cases and challenges we face in daily practice. Having the latest technique will enhance the possibilities of our treatment. We are looking forward to the solution that OXRAY and RayStation brings in.”
Johan Löf, Founder and CEO of RaySearch, remarked, "The OXRAY system represents a remarkable convergence of advanced radiotherapy technologies. By combining non-coplanar treatments, superior imaging capabilities, a conventional MLC, and real-time tracking, OXRAY delivers a new level of precision and flexibility. The integration with RayStation underscores our commitment to pioneering solutions that enhance cancer treatments.”
