TrueBeam™ STx with Novalis® Radiosurgery
What is Varian Truebeam?
Radiosurgery can be the treatment of choice for certain cancers. TrueBeam™ STx with Novalis® Radiosurgery is the latest in advanced radiosurgery technology from Varian Medical Systems and Brainlab. Redefining radiosurgery, TrueBeam STx with Novalis Radiosurgery is a technological leap forward. Performing a host of treatment techniques such as stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS), its power, accuracy and speed set it ahead of more conventional treatments.
Numerous features, like a High-Intensity Mode, multiple energy levels, high-definition beam shaping and very sophisticated imaging and motion management systems give clinicians game-changing tools to design optimal treatments for their patients. In fact, TrueBeam STx with Novalis Radiosurgery opens the door to new possibilities to treat cancer cases in the brain, lung, liver, pancreas and spine.
Beyond its impressive technical achievements, this technology was designed with many features that enhance patient comfort and improve the overall patient experience. With shorter treatment times and quieter operation, TrueBeam STx with Novalis Radiosurgery provides for a comfortable environment for patients. Enhanced communication technology enables a constant interaction between the patient and the therapist who operates the equipment. Three closed-circuit television systems enable the therapist to monitor the patient at all times. Music can be played during treatment, helping to increase patient comfort.
Innovation has a new name. That name is TrueBeam STx with Novalis Radiosurgery.

How Does Varian TrueBeam Work?
TrueBeam STx with Novalis Radiosurgery combines imaging, sophisticated and powerful beam delivery and advanced motion management to perform radiosurgery with great precision and speed.
Here are some quick facts:
- The machine rotates around the patient to deliver a prescribed radiation dose from nearly any angle.
- Precision is measured in increments of less than a millimeter.
- A high-definition multileaf collimator (or MLC) is what shapes the beam. It has 120 computer-controlled “leaves” or “fingers” that create apertures of different shapes and sizes. The leaves sculpt the beam to match the 3-D shape of the tumor. These can move and change during treatment to target the tumor and minimize dose to the surrounding healthy tissue.
- TrueBeam STx with Novalis Radiosurgery system’s additional functionality provides for the acquisition of a cone-beam CT, a form of CT, using 25% less X-ray dose than compared with earlier Varian image-guided technologies. This means patients can be exposed to less X-rays/radiation.
- Real-time imaging tools allow clinicians to “see” the tumor they are about to treat. This gives them confidence, and they can target tumors with accuracy measured in millimeters.
- The system includes a new “gated” option for synchronizing beam delivery with respiration. This helps maintain accuracy as the system changes its targeting whenever tumor motion is an issue, for example during lung cancer treatments.
- A patented High-Intensity Mode can deliver dose rates that are twice as fast as the current technologies
