Varian, a Siemens Healthineers company, announced 510(k) clearance from the U.S. Food and Drug Administration allowing sale of its RapidArc Dynamic solution, a ground-breaking technology leveraging advanced algorithms to revolutionize treatment planning to shorten the time between consultation to treatment.
Radiation therapy is part of the standard of care for roughly half of all cancer patients and has made significant strides over the years to minimize dose delivery to organs at risk. Precision in radiation therapy is crucial to improving post-treatment quality of life and reducing the risk of long-term complications as cancer patients live longer. For example, during treatment for breast or lung cancer, each gray (Gy) – a measure of radiation dose – that reaches the heart increases the relative risk of cardiac morbidity by 5%-7% and increases cardiac mortality by 1%-2%.
RapidArc Dynamic introduces advanced precision and control capabilities that have the potential to significantly reduce these risks in a single solution, while enabling efficiency. Early research has showcased the potential of RapidArc Dynamic, available as an optional feature for the latest version of Eclipse treatment planning software on the TrueBeam 4.1 radiotherapy delivery platform, to deliver significant benefits by reducing the dose to organs at risk by up to 50% and accelerating plan optimization and dose calculation by up to 70%. Additionally, early experiences showed that the number of treatment arcs could be reduced by as much as half.
RapidArc Dynamic is available as an optional feature for the latest version of Eclipse treatment planning software on the TrueBeam 4.1 radiotherapy delivery platform.
RapidArc Dynamic offers robust features designed to give care teams greater freedom and control in treatment planning and delivery:
- Next-generation algorithms empower clinicians to plan and deliver treatments more quickly and effectively, and handle a high volume of cases without compromising on quality in ways that were not possible on previous systems.
- Dynamic collimator can be adjusted in real time, and the gantry can be strategically paused during arc rotation to provide increased control to help ensure consistent and optimal dose delivery, combining the precision of modulated ports and arc therapy in a single treatment field.
- Simplifies workflows with built-in tools such as Auto-Skin Flash, which automates and simplifies a multi-step process, and streamlines workflow for advanced features including Multi-Criteria Optimization (MCO), RapidPlan, and clinical goals templates within the Eclipse treatment planning system.
