Varian secures FDA clearance for latest RapidArc technology

Siemens Healthineers company Varian has received clearance from the U.S. Food and Drug Administration (FDA) to sell the latest version of its radiotherapy technology, RapidArc Dynamic.

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, Varian said. According to the company, RapidArc Dynamic can reduce doses to organs at risk by up to 50% and accelerate plan optimization and dose calculation by up to 70%.

Key capabilities in the update include the following:

• Next-generation algorithms to help handle a high volume of cases in ways that were not possible on previous systems
• The dynamic collimator can be adjusted in real-time and the gantry can be strategically paused during arc rotation to provide increased control to ensure consistent dose delivery.
• Built-in tools such as Auto-Skin Flash, which automates a multistep process and streamlines workflow for advanced features, including Multi-Criteria Optimization (MCO), RapidPlan, and clinical goals templates within the Eclipse treatment planning system
