RayStation  supports carbon ion therapy with a module for carbon ion treatment planning, including handling of RBE-weighted dose. RaySearch is the market leader for heavy ions with the following five customers: MedAustron (Austria), CNAO (Italy), HIT (Germany), MIT (Germany) and Yamagata (Japan).



Carbon Pencil Beam Scanning planning*

RayStation provides the tools for designing and optimizing actively scanned pencil beam carbon ion treatment plans.

It includes a pencil beam dose engine to compute physical and RBE weighted dose according to the Local Effect Model. The optimizer can mix objectives for physical dose and RBE weighted dose. In the dedicated radiobiology application, you can define Local Effect Model parameters for the tissue sets to be used for planning. All plans are directly deliverable on synchrotrons after optimization, since the minimum spot weight is taken into account in the optimization, as well as other synchrotron specific machine constraints.


  • Already selected by five cancer centers
  • Fast GPU-based dose computation
  • Robust optimization including setup and range uncertainties
  • Multi-field and single-field optimization
  • Plan directly deliverable on synchrotrons
  • Combination planning with other modalities
* Regulatory clearance is needed in some markets.

The precision of proton therapy makes it a unique treatment method. A basic fact of proton therapy is that high precision also means sensitivity to change. RaySearch understands this, and we’ve designed the RayStation treatment planning system to account for every eventuality.

“We are extremely impressed by the flexibility and the dedication RaySearch has shown to implement our requirements in RayStation in such a short time. A great advantage when working with RaySearch has been their collaborative spirit and willingness to let us test, review and evaluate the system continuously. This has helped us define our priorities and contributed to a good learning process that ultimately led into a tailor-made proton and carbon ion treatment planning system.”

“MedAustron regards itself as an interdisciplinary and nationwide Austrian centre. It will specialize in cancer treatment with ions other than protons, the research and development of this new therapy and non-clinical research with ion and proton irradiation. 

Even amongst other similar centres, MedAustron is an unique project. There nearly is no off-shelf equipment for our specific requirements, concerning neither hard- nor software. One of the biggest challenges is therefore to find suppliers for all the needed equipment, who are able and willing to develop suitable devices according to our specific requirements. 

We chose RayStation because it's the most innovative system available and it's able to fulfill the high demands we make on our dose delivery system. From the first moment on RaySearch showed the flexibility and high competence, alike, necessary for such a demanding partnership.”
