Hitachi's new OXRAY image-guided radiotherapy system was utilized clinically for the first time at Narita Memorial Hospital in Japan, operating with RaySearch RayStation software.

OXRAY utilizes a gimbal-mounted beam delivery system, a pivoted support that allows an object to rotate around an axis while remaining stable and independent of its support's rotation. The image-guided radiation therapy system is designed to support motion management with moving object tracking illumination and gating capabilities, and utilizes two pairs of kV imagers built into the gantry.

Developed in collaboration with Kyoto University Hospital, the OXRAY system has been seamlessly integrated into RayStation through close collaboration between RaySearch and Hitachi. RayStation was used to drive its motion tracking functionality, dual-source CBCT image-guided radiotherapy for precise patient positioning, and dynamic swing arc capabilities.

Dr. Yuta Shibamoto, M.D. 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."

"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," said Johan Löf, founder and CEO of RaySearch. "The integration with RayStation underscores our commitment to pioneering solutions that enhance cancer treatments."

Narita Memorial Hospital, located in Toyohashi City, is part of the Meiyo-kai Hospital group, a distinguished healthcare provider founded in 1951. In 2012, it established itself as an early adopter of advanced radiotherapy techniques by introducing TomoTherapy. In 2018, it became the first healthcare facility in Japan to implement the IBA Proteus One system.

Founded in 2000 as a spinoff from the Karolinska Institute in Stockholm, RaySearch software has been sold to more than 1,000 centers in 43 countries.
