VARIAN ETHOS beam accelerator

The Radiotherapy Department of the National Center of Surgery is equipped with the latest adaptive radiotherapy device ETHOS, a modern and highly sophisticated artificial intelligence system from the well-known American company Varian.

▶ What is ETHOS radiotherapy?

ETHOS is the latest in artificial intelligence-powered radiotherapy technology. This technology is designed to bring new levels of precision and personalization to radiation therapy. Due to its adaptive therapy capabilities, the radiation dose can be instantly adjusted to the patient's anatomy.

▶ Main features and benefits:

Personalized treatment: During each treatment session, ETHOS adapts to the patient's unique anatomy, increasing the accuracy and safety of radiation therapy.

Real-time adaptation: ETHOS employs continuous visualization to modify the duration of treatment in response to modifications in the patient's anatomy, breathing, or position.

More comfort: By eliminating the need for repeated scans and immobilization equipment, the adaptive procedure enables patients to feel more at ease throughout treatment.

Decreased side effects: ETHOS lowers the chance of adverse effects and enhances patients' quality of life by reducing radiation exposure to healthy tissues.

Shorter treatment time: Adaptive treatment streamlines the process, potentially reducing the number of sessions required for treatment.

Diverse capabilities: ETHOS treatment is available for a wide range of cancers and stages.
