RaySearch Laboratories AB (publ) announced that the Mass General Cancer Center plans to expand its use of RayStation®? to proton treatment planning. RayStation is a flexible, innovative cancer treatment planning system developed by RaySearch.

The software offers features for proton therapy planning such as multi-criteria optimization, LET evaluation, and optimization, as well as modalities under development such as proton arcs and FLASH. The Mass General Cancer Center, which was the first in the world to offer proton therapy, is in the process of transitioning its proton treatment planning system to RayStation. The center has been using RayStation for photon radiation therapy planning for more than 10 years.

By expanding its clinical use to include protons, all external beam planning will now be done on a single platform.
