What Is TrueBeam?
TrueBeam is an advanced radiosurgery system from Varian Medical Systems that delivers treatment with speed and accuracy.
TrueBeam synchronizes a treatment beam system (that provides the beams of radiation for treatment) to an imaging system (that allows doctors to see the tumor they’re treating). It also has very sophisticated respiratory monitoring systems that compensate for your breathing as it targets tumors in the thorax and abdomen. Because treatments are noninvasive, there is no incision or surgery with TrueBeam. The ability to deliver higher doses of radiation at great speed allows most treatments to be given in just minutes a day.
TrueBeam Is Truly Unique. Here Are Some of the Ways It Is Different.
- TrueBeam is an advanced technology that gives doctors the flexibility to customize treatments for an individual’s particular cancer, including some of the more challenging cases in places like the brain, lung. liver, pancreas and prostate.
- TrueBeam performs advanced treatments like stereotactic body radiotherapy (also known as SBRT) and stereotactic radiosurgery (SRS). This gives your doctor the opportunity to tailor your treatment-to choose a method this is best for your particular case.
Fast, precise treatments
TrueBeam is finely engineered to be fast and precise with most treatments taking just minutes a day.
- In fact, even tumors that move (for example, those in the lungs) can be precisely targeted thanks to special tools that compensate for motion during a treatment.
- The imaging systern on the TrueBeam will let your doctor visualize, in real time, the tumor that is being treated. 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.
- Every tumor is different, and TrueBeam can sculpt and shape the radiation beam to accurately match the size and form of just about any tumor regardless of its shape. It uses a device called a multileaf collimator that has 120 computer-controlled “leaves” or “fingers” that can move to create an aperture of different sizes and shapes. During treatment, this aperture changes to target the tumor and minimize exposure to the surrounding healthy tissue.
