Narita Memorial Proton Center, Japan, treats first patient with the treatment planning system RayStation

Narita Memorial Proton Center in Toyohashi, Japan, has treated its first patient using planning in RayStation. The system was used to plan a pencil beam scanning treatment (PBS) which was delivered to a prostate cancer patient by the IBA Proteus®ONE compact proton therapy solution.

The center was established in April 2018, and this first patient treatment was conducted in early September.

The RayStation system at Narita Memorial Proton Center includes multi criteria optimization (MCO), which seeks to decrease manual planning time, provide a better understanding of tradeoffs between conflicting planning goals, and improve treatment plan quality.

Japan is one of the world's most technologically advanced treatment planning markets, and particle planning is continuously growing in the region. RaySearch has a strong user base in Japan and is a world-wide market leader for proton therapy planning software.

Takeshi Yanagi, Director Narita Memorial Proton Center, says: “It was smoother to create treatment plans than we expected. We really felt this was the right system for us when RaySearch could demonstrate that it will be possible to evaluate the treatment plans with respect to robustness.”

Johan Löf, CEO of RaySearch, says: “We are very happy to see another state-of-the-art proton center in Japan using RayStation for its first clinical treatment. Narita Memorial Proton Center is recently established, and we are looking forward to many more years of successful cooperation.”
