- Next-generation algorithms generate treatment plans in seconds, accelerating plan optimization and dose calculation by up to 70%.
- Improved dose coverage from dynamic collimator and modulated ports potentially reduces the number of treatment arcs needed by as much as half, while reducing dose to organs at risk by up to 50%.
- Simplifies workflows with new automated tools and leverages existing advanced features within Eclipse treatment planning system.
PALO ALTO, Calif., Dec. 18, 2024 /BUSINESS WIRE/ -- 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%.1,2,3 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 the latest example of Varian’s sustained investment in innovation, and ushers in a radical transformation in radiotherapy planning and delivery designed to bring flexibility to care teams using for arc therapy,” said Sasa Mutic, PhD, President, Radiation Oncology Solutions for Varian. “The increased efficiency of RapidArc Dynamic to optimize plans has the potential to help decrease the time between diagnosis and treatment. Combined with significant radiation dose improvements, this is a major step in our field.”
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.
“RapidArc Dynamic represents a powerful new solution for personalizing treatment planning and delivery with the potential to further reduce doses to organs at risk which can help reduce toxicities without disrupting treatment workflow,” Sushil Beriwal, MD, Vice President, Digital Oncology, Medical Affairs for Varian. “This new flexibility aims to help care teams reach new milestones in improving treatment outcomes.”
* All the FDA 510(k) clearances are in place to support the RapidArc Dynamic solution.
CE Marked. 510(k) cleared. Not available for sale in all markets and no guarantee of commercialization or feature availability.
