One of the most innovative radiation therapy tools available today, Varian's Trilogy™ system combines new image-guidance technology with one of the most powerful and precise radiation beam available. As a result, Trilogy™ shortens cancer treatment times and targets tumors more precisely.

Tumor tissues can move, both between radiation treatments and during a treatment, because of breathing and other involuntary movement. Trilogy™ tracks a tumor's location during treatment and synchronizes radiation therapy with the moving target. This versatile technology's real-time imaging provides us with up-to-the-second data and enables us to monitor tumor motion throughout treatment. This means we can deliver optimal doses of radiation with increased accuracy and avoid harm to nearby healthy tissues.

Furthermore, the speed at which Trilogy™ administers radiation treatment is significantly faster than some other radiation therapy systems. Trilogy™'s RapidArc™ radiotherapy technology shortens treatment times to one-half to one-eighth that of conventional treatments-quickly, efficiently and safely. In a single rotation, the machine revolves around the patient, delivering a sculpted beam of radiation to the tumor.

Trilogy™ also offers multi-treatment functionality in a single machine. Our radiation oncologists use a variety of techniques to deliver treatment that meets each patient's individual needs, including Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT) and Stereotactic Body Radiotherapy (SBRT) - all from one machine.
