MedStar Georgetown University Hospital now clinical with RayStation and Hyperscan

Report this content

MedStar Georgetown University Hospital in Washington, D.C., has begun patient treatments using the RayStation treatment planning system in combination with Mevion’s Hyperscan pencil beam scanning system. This was the world’s first treatment carried out on the Mevion S250i Proton Therapy System®.

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

RayStation enables the use of advanced IMPT capabilities that are unique to the Hyperscan technology, including multi-leaf collimation with Mevion’s Adaptive Aperture, a proton multi-leaf collimator (pMLC) designed to achieve sharp lateral dose gradients and protect sensitive organs at every energy layer of the treatment.

Johan Löf, CEO of RaySearch, says: “We are very pleased to see this groundbreaking patient treatment at MedStar Georgetown, using RayStation in combination with Mevion’s Hyperscan technology. Proton therapy is an important focus area and RaySearch is committed to supporting all the latest techniques and systems. Together we will ensure that more and more patients can benefit from this high-precision form of treatment.
