RaySearch Laboratories, a medical technology company, has obtained 510(k) clearance for the extended version of its RayStation 4.0 treatment planning system that contains tools for optimization of proton treatments using the pencil beam scanning technique (PBS).


The extended version of RayStation 4.0 treatment planning system had received CE Mark approval in December 2013.

With the 510(k) clearance, RaySearch can now market the new version of RayStation 4.0 in the US.

PBS, the most sophisticated technique to deliver proton therapy, enables intensity modulated proton therapy that allows clinicians to target a cancerous tumor by controlling both the intensity and the spatial distribution with millimeter precision.

According to RaySearch, RayStation’s proton module features all the tools required for PBS such as multiple field optimization, single field uniform dose and distal edge tracking techniques.

RaySearch CEO Johan Lof said that the company has won several orders and been the most successful supplier of solutions for proton treatment planning over the last year.

"Our position on the US market becomes even stronger now that we have market clearance for all relevant techniques for proton therapy" Lof added..

Built on the latest software architecture, RayStation integrates all RaySearch’s advanced treatment planning solutions into a flexible treatment planning system and has a graphical user interface offering great usability.

RayStation combines features such as multi-criteria optimization tools with full support for 4D adaptive radiation therapy.

It includes functionality such as RaySearch’s market-leading algorithms for intensity-modulated radiation therapy and volumetric modulated arc therapy optimization and highly accurate dose engines for photon, electron and proton therapy.
