CARBON ION PLANNING*

RayStation 5* includes a new module for carbon ion treatment planning. MedAustron in Wiener Neustadt in Austria and Centro Nazionale di Adroterapia Oncologica (CNAO) in Pavia, Italy, are the first centers to use RayStation this new planning technology.

* Regulatory clearance is needed in some markets.

 

Carbon Pencil Beam Scanning planning/ rayCarbonPlanning*

With rayCarbonPlanning, 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 dose and RBE weighted dose according to the Local Effect Model. The optimizer can mix objectives for physical dose and RBE weighted dose. 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.

In the rayBiology application, the user can define LEM model parameters for the tissue sets to be used for planning.

  • Optimization of pencil beam scanning using multi field optimization and distal edge tracking techniques.
  • Step-and-shoot spot scanning
  • Manual editing of spot pattern
  • Spot visualization
  • Spot weight filtering
  • Range shifter support
  • Editable snout position
  • Control of initial spot selection with respect to target and OARs
  • Optimization including lower limit of spot MU delivery
  • Layer repainting
  • Spot order sorting through scan path length optimization

“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.”
