RayStation 3.5 treatment planning system released
RaySearch Laboratories has released version 3.5 of its RayStation oncology treatment planning system for clinical use in the EU, US, Japan and Australia. The system is also pending regulatory approval in Canada, China, New Zealand and South Korea.
Witht RayStation 3.5, RaySearch releases state of-the-art tools for treatment planning of radiation therapy with electrons and protons, complementing its extensive tools for planning and optimisation of radiation therapy with photons. Proton Beam Design is a new module in RayStation that contains tools for treatment planning of double-scattered and uniformly-scanned protons, such as a pencil beam dose engine and automatic generation of treat-and-protect beams. This is the first clinical release of proton planning functionality in RayStation, to be followed by others, such as pencil beam scanning techniques and Monte Carlo dose calculations. Electron Beam Design is another new module that includes a Monte Carlo dose engine for electron radiation therapy and tools for manual editing of beams similar to the process in the RayStation 3D-CRT module. The functionality for Proton Beam Design and Electron Beam Design is available for installation in the EU, Japan and Australia but is pending regulatory clearance in US.
RayStation 3.5 also adds new features to the existing IMRT and VMAT modules offering the possibility to perform all IMRT and VMAT delivery modes available with all relevant machines from hardware suppliers. One example is the introduction of support for IMRT treatments using the DMLC delivery mode (sliding window). Another example is support for mARC that enables treatment planning of rotational therapy with Siemens linacs. On top of support for all treatment modalities, RayStation 3.5 also offers a wide range of new tools for improving the planning workflow and automating tedious treatment planning tasks for example introduction of plan generation protocols.
Fallback Planning has significant potential to save planning time. This function provides a way to automatically generate treatment plans for alternative treatment machines and techniques, based on an existing dose distribution. This enables clinicians to switch patients from one treatment machine to another to balance the workload or as a back-up, in case the designated treatment machine is unavailable at the scheduled time of a treatment. Other major features included in RayStation 3.5 are biological evaluation and biological optimisation. These give the user the opportunity to evaluate the radiobiological effect of a treatment using the most well-established radiobiological effect models or optimise the treatment based on a mix of physical and radiobiological objectives and constraints.
Furthermore, the new release includes a wide range of other highly useful features such as a new function for automatic reduction of organ-at-risk doses, tools for letting the user define MBS models and user-configurable treatment plan reports. In addition, RayStation 3.5 includes major improvements and performance enhancements that further facilitate and speed up the treatment planning process in modules such as RayPhysics, Treatment Adaptation, Multi-Criteria Optimisation and DICOM import and export.
