The Varian TrueBeam linear accelerator integrates imaging and radiation delivery. It can be used to deliver numerous forms of radiotherapy, and gives your doctor the opportunity to tailor your treatment and choose the method that is best for your particular case. TrueBeam synchronizes radiation dosage, real-time tumor tracking and imaging (Image-Guided Radiation Therapy or IGRT) with millimeter precision. It delivers 3D-Conformal radiation therapy, Intensity-Modulated Radiation Therapy (IMRT), RapidArc Radiotherapy, Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT), all from one system.
TrueBeam has an On-Board Imager (OBI) controlled by two robotic arms that rotate around you to create a three-dimensional picture to confirm the location of the tumor. TrueBeam then provides a precisely sculpted 3D radiation dose as it rotates 360º around you. The system continuously monitors the movement of your tumor as you breathe (“respiratory gating”) and only delivers radiation when the tumor is in exactly the right place. This allows for a higher, more effective dosage amount without additional risk of side effects, including damage to normal, surrounding tissues.
RapidArc technology is built into the Varian TrueBeam Linear Accelerator system, providing a very precise radiation therapy treatment in less than two minutes while maintaining the accuracy of the treatment. The system even allows music to be played during treatment, helping to enhance your comfort.
