RRH Strengthens Regional Cancer Care with Installation of Ethos Adaptive Radiation Therapy

February 24, 2026|1 min. read

ROCHESTER, N.Y.— Rochester Regional Health (RRH) is celebrating another significant advancement in regional cancer care with the installation of the Ethos Linac Adaptive Radiotherapy system at Rochester General Hospital.

This state-of-the-art system uses daily CT imaging, artificial intelligence (AI) and a rapid replanning process to generate customized treatment plans in real time for each patient, accounting for natural anatomical changes that may occur between treatments. Physicians review and approve each aspect of the plan, maintaining full clinical decision-making authority while ensuring care reflects the patient’s body at that specific moment.

This adaptive approach enables personalized, adaptive radiation therapy and allows clinicians to deliver less radiation to healthy tissue while administering more radiation precisely to the tumor. Integrating this technology increases confidence in treatment accuracy and may streamline planning and delivery, improving efficiency for both patients and care teams. For patients, this approach may translate into fewer treatment sessions and a more efficient course of care, with greater precision throughout the process.

“This technology represents an important step forward in the way we deliver radiation therapy,” said Dr. Jeffrey Haynes, Executive Medical Director of Cancer Services for RRH “By adapting treatment in real time, we can better protect healthy tissue while targeting tumors with greater accuracy. It underscores our ongoing commitment to bringing innovative, patient-centered cancer care to our community.”

The addition of the Ethos system to RRH’s comprehensive cancer care program not only strengthens its existing radiation oncology services, but also expands access to highly personalized, precision-driven adaptive radiotherapy. This technology ensures that more patients in our region can benefit from some of the most advanced, responsive cancer treatment available today, right here in Rochester.
