MedStar Georgetown Proton Center Selects RayStation for Treatment Planning

Washington D.C. center will combine treatment planning system with Mevion S250i proton therapy system to deliver advanced intensity modulated proton therapy

MedStar Georgetown Proton Center Selects RayStation for Treatment Planning

August 17, 2017 — The proton center at MedStar Georgetown University Hospital will utilize RayStation for planning on the Mevion S250i Proton Therapy System with Hyperscan when the facility opens for treatment later this year. The RayStation treatment planning system will enable the utilization of advanced intensity modulated proton therapy (IMPT) capabilities that are unique to the Hyperscan technology, including multi-leaf collimation with Mevion’s Adaptive Aperture.

The combination of RayStation and Mevion’s Hyperscan technology will enable clinicians at MedStar Georgetown to plan and treat patients with the advantage of very sharp field edges and minimized radiation to critical structures.

RayStation integrates all RaySearch’s advanced treatment planning solutions into a flexible treatment planning system. It combines features such as multi-criteria optimization tools with full support for 4-D adaptive radiation therapy. It also includes functionality such as RaySearch’s algorithms for intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) optimization and highly accurate dose engines for photon, electron, proton and carbon ion therapy. The system is built on the latest software architecture and features a graphical user interface with state-of-the-art usability, according to RaySearch.
