TrueBeam STx Radiotherapy/Radiosurgery

Precision plus speed of treatment equal an unprecedented era in cancer care.  

Sharp HealthCare offers the TrueBeam STx™ radiotherapy/radiosurgery system for patients undergoing image-guided radiotherapy (IGRT), intensity-modulated radiotherapy (IMRT), RapidArc® radiotherapy and Gated RapidArc. TrueBeam is the most advanced cancer treatment technology currently available.

TrueBeam's pinpoint precision and speed represents an unprecedented era in cancer care. Physicians use TrueBeam for nearly all types of cancer, especially those that are difficult to precisely target because they move, such as kidney, liver, lung and breast. TrueBeam also allows for new possibilities in treating brain tumors.

How Does It Work?
Combining imaging with treatment, TrueBeam's imager guides patient placement, while the machine rotates around the patient to deliver radiation treatment from nearly any angle.   

The radiation beam is sculpted to match the three-dimensional shape of the tumor. This is done using a multileaf collimator (MLC), a device with 120 computer-controlled mechanical "leaves" that can move to create different shapes and sizes. Because of the system's tremendous precision, full doses of radiation can be delivered quickly and accurately to the tumor with little or no damage to healthy surrounding tissue.  

TrueBeam's advanced communication technology allows for constant contact between the patient and therapist operating the equipment. Additional features allow music to be played during treatment, helping to create a more soothing environment.

Why Does Speed Matter?
Faster radiotherapy treatments are typically easier on patients, who do not need to hold still for long periods of time. In addition, by reducing the time it takes to deliver radiotherapy, X-ray doses are typically 25 percent less than other treatments.

Benefits of TrueBeam
The benefits of TrueBeam include:

  • Offers radiation therapy that is fast and extremely precise — a single treatment session is typically 10 minutes or less
  • Delivers less X-ray than other treatments
  • Offers new treatment options for patients with complex types of cancer or who may not be candidates for traditional radiotherapy
  • Allows for new treatment possibilities on hard-to-treat cancers, such as brain
  • Allows treatments to be tailored to patient's specific needs
