By GlobalDataThis latest iteration of the Ethos system significantly increases the number of AI-segmented anatomical structures that can be contoured automatically, now including more than 70 structures in the head and neck, thorax, abdomen, pelvis, and bowel regions.
This advancement aims to reduce the manual, time-intensive process of contouring.
The new generation of the Ethos system also enhances data sharing capabilities and exchange with the ARIA CORE oncology management solution, streamlining effective patient management.
Varian head Arthur Kaindl said: “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.
“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.”
Data from Varian indicates that clinicians using Ethos have preferred the adapted treatment plan in 88% of cases, demonstrating its benefit for patient care.
The Ethos system offers the flexibility of online or offline adaptation, as well as conventional image-guided radiotherapy, making it a versatile option for clinicians.
