TrueBeam Radiation Therapy

TrueBeam is a highly advanced, computerized system that enables Institute doctors to very specifically and very effectively target cancerous cells with radiation therapy. We have the system in our office, which enables the Institute to provide our patients with all aspects of treatment in one location.

The TrueBeam is a state-of-the-art radiotherapy system that uses nonin­vasive tumor-destroying radiation to treat cancers throughout the entire body (head, lung, breast, prostate, skin, etc.) as it minimizes exposure to surrounding healthy tissue.

TrueBeam performs many advanced forms of radiotherapy. These include intensity-modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT) and Stereotactic Radiosurgery (SRS) or Stereotactic Body Radiotherapy (SBRT). IMRT is a treatment technique where doctors are able to customize your radiation dose by varying (or modulating) the amount of radiation that is sent to different parts of your tumor.

IGRT uses advanced imaging so doctors can visualize your tumor. This allows them to verify the exact position of the tumor and treat it precisely during each treatment appointment. SRS and SBRT are techniques where doctors precisely target a small area in your brain (SRS) or other parts of your body (SBRT) with great precision and accuracy with only 1 to 5 treatments.

TrueBeam also uses an advanced motion management system which synchronizes a beam system (that provides the beams of radiation for treatment) to an imaging system (that allows doctors to “see” the tumor they’re treating) to compensate for moving targets. Because treatment delivery is noninvasive, there is no incision or surgery with TrueBeam.

The ability to deliver higher doses of radiation at great speed with TrueBeam RapicArc technology allows most treatments to be given in just a few minutes a day thus minimizing discomfort and interruptions to your daily life.

Every tumor is different, and TrueBeam can 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.

During your treatment, continuous video and two-way audio with the therapist allows you to communicate easily throughout your treatment. TrueBeam runs smoothly and quietly. Advanced features allow music to be played during treatment, helping to enhance your comfort.
