ASTRO '18: RaySearch showed power of automation with machine learning applications

By News Release


RaySearch showcased its latest development in machine learning technology and automation in both RayStation*, the innovative treatment planning system (TPS) and RayCare*, the groundbreaking oncology information system (OIS), at the American Society for Radiation Oncology (ASTRO) 2018 annual meeting in San Antonio.

Machine learning and automation in RayStation

With its in-house machine learning department, RaySearch is currently developing machine learning and deep learning prototypes for areas such as treatment plan generation, organ segmentation and target volume estimation. RaySearch is also developing techniques for efficient large-scale data extraction and analysis. The first clinical applications of machine learning are automated treatment planning and automated organ segmentation and will be included in the next RayStation release* in December. These applications will revolutionize the way radiation oncology treatment planning is done and offer an enormous efficiency boost for cancer clinics.

RayCare in clinical use

The RayCare next-generation OIS is now directly connected to the treatment delivery system at the Provision Cares Proton Therapy facility in Nashville, US. RayCare is used to manage the treatment sessions. The Nashville center treated their first patient on October 8 and utilizes the RayCare OIS together with the RayStation TPS to plan and manage its proton treatments. RayCare 2B was released early October. This version introduces new features and usability improvements throughout the system, including a feature to support a full treatment delivery and management workflow and task-based offline image review. Other care administration features include support for financial information, such as insurance information and authorization management, and support for managing external contacts, referring clinicians and other external entities.

Joint demonstrations

Online adaptive proton therapy workflow with IBA

IBA and RaySearch presented their online adaptive proton therapy workflow*, where daily optimized plans are created for the individual patient, based on cone-beam CT images to preserve the original treatment intent. Both companies offered demonstrations including RayCare, RayStation, the AdaPT Insight imaging platform and the AdaPT Deliver treatment delivery. The solution can automatically suggest, to the care team, an adapted treatment plan which considers the most up-to-date patient’s anatomy. This workflow offers more accurate treatment plans as well as faster plan adaptation to the benefit of patients.

Support for TomoTherapy treatment management and planning

In the Accuray booth, presentations of RayStation and RayCare for the TomoTherapy® platform were available. RayStation 8A, released earlier this summer, includes full support for the TomoTherapy and Radixact Systems. All TomoTherapy and Radixact users can now get access to advanced RayStation features, including multi-criteria optimization (MCO), adaptive planning and Plan Explorer. RaySearch deputy CEO Björn Hårdemark held a presentation at Accuray’s AEROTM Academy; the theme of his talk was “Full Integration of TomoTherapy, RayStation and RayCare.”
