Deep learning and machine learning in RayStation

New functionality from the latest releases of RayStation will be demonstrated, including the first-ever deep learning and machine learning applications in a treatment planning system. The applications for automated treatment planning and automated organ segmentation, which are a part of RayStation 8B, will help improve efficiency and consistency in radiotherapy at the clinic.  

The efficiency gains from the machine learning features in RayStation 8B was recently published. RaySearch and University Medical Center Groningen in The Netherlands have conducted a retrospective clinical study on head-and-neck cases. The study shows that the machine learning planning approach can generate deliverable dual arc VMAT plans with adequate target coverage in 97% of the cases. The results will be presented during the lunch symposium Advancing Cancer Treatment Through Software Innovation on Saturday April 27.

RaySearch is collaborating with Iridium Cancer Network, Antwerp, Belgium, on deep-learning segmentation, and the clinic has trained a model for male pelvic segmentation. The results will be shown at the congress and can be read further upon in the Deep learning segmentation whitepaper at RaySearch's website.  

Other new major functionalities in RayStation will be demonstrated, including photon Monte Carlo dose calculation, a new module for evaluation of robustness of treatment plans, as well as the availability of boron neutron capture therapy (BNCT) planning*.

How the clinical use of RayCare can increase workflow efficiency

RayCare is in clinical use at Iridium Cancer Network and at the newly opened Provision Cares Proton Therapy in Nashville, USA, where RayCare is being used as the sole OIS. Representatives from both clinics will participate during the lunch symposium on Saturday April 27, where the workflow efficiency gains from the integration between RayCare and RayStation will be discussed.

The development of RayCare is moving forward rapidly and the latest features and improvements will be demonstrated at ESTRO 38. Efficiency boosting features include task-based order management which automatically triggers workflows, improved planning workflow using automated plan generation from RayStation, as well as patient summary and whiteboard views.

Demonstrations

Support for TomoTherapy® treatment planning and management
In the Accuray booth, presentations of RayStation and RayCare for the TomoTherapy® platform will be available. Demonstrations can be booked by visiting RaySearch's and Accuray's respective booths.

RaySearch's deputy CEO Björn Hårdemark will hold a presentation at Accuray's AERO™ Academy on Monday, April 29 at 13:10 pm. The theme of his talk is "Full Integration of the TomoTherapy® System, RayStation and RayCare".

Online adaptive proton therapy workflow
The online adaptive proton therapy workflow will be presented. Daily optimized plans are created for the individual patient to preserve the original treatment intent. Demonstrations can be booked by visiting RaySearch's booth.

Proton planning for MEVION S250i Proton Therapy System®
RayStation now supports Adaptive Aperture pencil beam planning, where each delivered energy layer is collimated separately. This new feature brings out the best of the MEVION S250i Proton Therapy System with HYPERSCAN® Pencil Beam Scanning. Demonstrations can be booked by visiting RaySearch's and Mevion's respective booths.
