TrueBeam Radiotherapy System

In 2010, the John Theurer Cancer Center Radiation Oncology Department became the first cancer center in New Jersey to acquire TrueBeam™, an innovative system that enables a radically different approach to treating cancer with image-guided radiotherapy (IGRT). We are also the only cancer center in the country with two machines. TrueBeam enables the John Theurer Cancer Center to treat even the most challenging cases with unprecedented speed and accuracy.

The TrueBeam system, from Varian Medical Systems, was engineered from the ground up to deliver more powerful cancer treatments with pinpoint accuracy and precision. It uniquely integrates new imaging and motion management technologies within a sophisticated new architecture that makes it possible to deliver treatments faster while monitoring and compensating for tumor motion, opening the door to new possibilities for the treatment of lung, breast, prostate, head and neck, as well as other cancers that are treatable with radiotherapy.

This state-of-the-art radiotherapy system allows the John Theurer Cancer Center to offer even faster treatments, enhanced accuracy, and quicker imaging at lower doses.

  • With dose delivery rates that are 40-140 percent higher than earlier generations of Varian technology, simple treatments that once took 15 minutes or more can be completed in less than two minutes once the patient is in position.
  • “Intelligent” automation further speeds treatments with an up to five-fold reduction in the number of steps needed for image guidance and dose delivery.
  • The precision is measured in increments of less than a millimeter. This accuracy is made possible by the system’s sophisticated architecture, which synchronizes imaging, patient positioning, motion management, beam shaping, and dose delivery, performing accuracy checks every ten milliseconds throughout the entire treatment.
  • For lung and other tumors subject to respiratory motion, this system makes it possible to monitor patient breathing and to compensate for tumor motion while quickly delivering a dose during a continuous rotation around the patient.
  • This radiotherapy system will allow physicians to choose an imaging mode that minimizes the amount of X-rays needed to generate an image. The imaging technology can produce the three-dimensional images used to fine-tune tumor targeting in 60 percent less time and the additional functionality makes it possible to create images using 25 percent less X-ray dose.
