Varian, a Siemens Healthineers company, has received U.S. 510(k) clearance for new features in its Ethos therapy system. The updated system offers a simplified workflow for daily treatment adaptation across more body areas and improved connectivity to patient data, reducing complexity and enhancing the implementation of adaptive, personalized radiotherapy.

New and Updated Features

Ethos 2.0 provides clinical teams with these features to optimize clinical and operational efficiencies:

  • Enhanced algorithms in the Ethos Intelligent Optimization Engine (IOE) improve treatment planning and dose delivery for faster treatment.
  • Images acquired using the HyperSight imaging solution are integrated into the software to streamline workflows and enable direct dose calculation for adapting treatments. This allows clinicians to create a treatment plan based on the day’s anatomy more easily and accurately.
  • The system automatically contours over 70 anatomical structures in the head & neck, thorax, abdomen, pelvis, and bowel regions, reducing the need for manual contouring.
  • The latest generation optimizes clinical and operational efficiencies by facilitating seamless data sharing with the ARIA CORE oncology management solution.

AI-Powered Treatment Precision

“Our latest Ethos system reflects our ongoing commitment to develop innovative solutions that make real-time, adaptive radiotherapy treatment easier to accomplish in any setting,” says Arthur Kaindl, head of Varian. “By reducing workflow complexity, leveraging advanced, AI-powered technology, and enabling greater connectivity to patient data across our ecosystem, we continue to invest in comprehensive tools to help clinicians integrate precision throughout the patient journey.”

Since its launch in 2019, the Ethos system has been widely used in radiotherapy. Varian data indicate that providers chose the adapted treatment plan 88% of the time for patient benefit. The Ethos system allows clinicians to choose between online or offline adaptation or conventional image-guided radiotherapy.
