TrueBeam STx

TrueBeam STx

TrueBeam STx is an advanced radiosurgery system that delivers treatment with speed and accuracy. 

TrueBeam STx 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 STx. The ability to deliver higher doses of radiation at great speed allows most treatments to be given in just minutes a day. 

TrueBeam STx is unique. Here are some of the ways it is different. 

Personalized treatments

  • TrueBeam STx 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 STx performs advanced treatments like stereotactic body radiotherapy (also known as SBRT) and stereotactic radiosurgery (SRS). This gives the doctor the opportunity to tailor treatment – to choose a method this is best for a particular case. 

Fast, precise treatments 

TrueBeam STx 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 system on the TrueBeam STx will let the 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 image-guided technologies.
  • Every tumor is different, and TrueBeam STx 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 high-definition (HD) 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.
