October 29, 2018 — RaySearch exhibited its latest advances in oncology software at the 2018 American Society for Radiation Oncology (ASTRO) annual meeting, Oct. 21-24 in San Antonio, Texas, backed by machine learning and user-friendly tools to enable optimal use of clinical resources. The company showed its latest development in machine learning technology and automation in both its RayStation treatment planning system (TPS) and RayCare oncology information system (OIS).
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.
The RayCare next-generation OIS is now directly connected to the treatment delivery system at the Provision Cares Proton Therapy facility in Nashville. RayCare is used to manage the radiation therapy treatment sessions. The Nashville center treated their first patient on Oct. 8 and utilizes the RayCare OIS together with the RayStation TPS to plan and manage its proton treatments.
RayCare 2B was released early October and was displayed at the show. 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.
RaySearch also offered joint product demonstrations with other ASTRO 2018 exhibitors, including:
- IBA and RaySearch presented their online adaptive proton therapy workflow, where daily optimized plans are created for the individual patient based on cone beam computed tomography (CBCT) 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 that considers the most up-to-date patient anatomy. This workflow offers more accurate treatment plans as well as faster plan adaptation to the benefit of patients;
- 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; and
- Mevion Medical Systems showed the latest proton therapy news with the Mevion S250i system with Hyperscan Pencil Beam Scanning demonstrations, using RayStation.
