RaySearch Laboratories AB signed an agreement for RayStation® with Proton International Arkansas for the Radiation Oncology Center, which is part of the University of Arkansas for Medical Sciences (UAMS) Winthrop P. Rockefeller Cancer Institute. The UAMS Radiation Oncology Center will open in 2023 and be the first proton center in the state of Arkansas. It will use RayStation treatment planning system.

The software selected by Proton International Arkansas include advanced technologies such as IMPT (intensity modulated proton therapy), multi-criteria optimization, and full adaptive planning capabilities, along with conventional photon and electron IMRT /VMAT (intensity modulated radiation therapy and volumetric modulated arc therapy). The center at UAMS brings RaySearch's presence in proton therapy to thirty centers in the United States, a large majority of operating facilities. Customers attribute this popularity to the advanced features on a single platform with cutting edge performance in speed and quality, along with RaySearch's experience and expertise in getting these centers up and running quickly and safely.
