“The Trilogy system is a powerful, precise and versatile treatment machine that can be used to deliver advanced forms of radiotherapy, including accurate stereotactic approaches for treating very small lesions quickly and accurately. We can use it to deliver any type of radiotherapy, including intensity modulated radiotherapy (IMRT), image-guided radiotherapy (IGRT), stereotactic body radiotherapy (SBRT), stereotactic radiosurgery (SRS) and RapidArc® radiotherapy,” said Dr. Robert Ebeling, NLCI Medical Director.
At the core of the Trilogy system is Varian’s high-powered medical linear accelerator, a machine that rotates around the patient to deliver radiotherapy treatments from virtually any angle. The system is able to concentrate radiation doses on the tumor while minimizing exposure of surrounding healthy tissue.
“The Trilogy system is proven technology that will enable us to offer advanced image-guided radiotherapy for a broad spectrum of cancer patients,” said James Adams, Executive Director. “It provides our physicians with tremendous versatility and precision for customizing treatments and for choosing an appropriate delivery approach based on the specifics of each patient’s case. The NLCI is proud to offer this state-of-the-art treatment technology to our community.”
Targeting Tumors Accurately
Trilogy also incorporates an X-ray imager that can generate 2-D, 3-D and moving images of the tumor and surrounding anatomy. For accurate tumor targeting, the patient’s position is adjusted based on these real-time images prior to treatment. A beam-shaping device called a multileaf collimator continually shapes and reshapes the radiation beam to match the three-dimensional shape of the tumor as the machine rotates around the patient during treatment.
Fast, Precise Treatment
The Trilogy system can be used for RapidArc ® radiotherapy treatments. RapidArc delivers fast, precise image-guided treatments during a continuous rotation around the patient, with many treatments delivered in two minutes or less.
Stereotactic Approaches to Treatment
The Trilogy linear accelerator is capable of stereotactic applications that involve delivering high doses of radiation to small areas over short periods of time.
“Stereotactic approaches are generally most appropriate for small lesions and early metastases,” said Dr. Ebeling. “Better diagnostic tools are making it possible for us to see tumors much earlier, when they’re still very small, so stereotactic radiotherapies are likely to play a much larger role in the future of cancer care.”
“Radiotherapy is an integral component in the treatment of cancer,” said Dr. Ebeling. “Using the image guidance, beam shaping and motion management tools available with the Trilogy system, we can protect healthy tissue while delivering more powerful radiation doses to tumors.” The Trilogy is an added compliment to the already heavy arsenal of technology at the Northeast Louisiana Cancer Institute. This is the third Varian system at NLCI. The Trilogy will be housed in NLCI’s West Monroe facility inside of Glenwood Regional Medical Center.
