During 27–29 April, RaySearch will be exhibiting at the ESTRO 38 Annual meeting in Milan, Italy. RaySearch will demonstrate machine learning* and deep learning* features in the treatment planning system RayStation® and present related studies and results. The latest innovations in the groundbreaking, now clinically live, oncology information system (OIS) RayCare®* will also be on show. Attendees are welcome to visit RaySearch at booth #1100. Demonstrations are already available for booking at: www.raysearchlabs.com.
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.
