Trilogy

For Physicians

UMGCC physicists conduct quality assurance tests on the Trilogy linear accelerator

The addition of The TrilogyTM System means that we are now able to offer every modality of external beam radiation therapy, from conventional radiotherapy and intensity-modulated radiotherapy (IMRT) to the newest and most advanced techniques available: image-guided radiotherapy (IGRT), stereotactic radiotherapy (SRT), and high-dose stereotactic body radiation therapy (SBRT).

See Technology Comparison Chart (pdf).

With Trilogy, we have the option to treat small lesions using stereotactic radiosurgery -- delivered in a single treatment; or stereotactic radiotherapy -- delivered over a few days; as well as more traditional forms of radiotherapy.

Trilogy includes technology for positioning the patient exactly, using images of the tumor and surrounding anatomy taken just prior to each treatment. The images are used to verify tumor position immediately before the radiation beam is turned on. This gives us the ability to maximize the dose to the tumor, and minimize the dose to surrounding healthy tissue.

The respiratory gating system automatically turns the beam off and on to compensate for breathing motion during treatment. This keeps the radiation beam focused on the tumor, and further protects normal healthy tissues.

The TrilogyTM System can shape a beam with sub-millimeter accuracy, and offers the highest dose rates available, to deliver a potent punch of radiation in a short amount of time. This combination of precision and power allows Trilogy to reduce both treatment times and side effects, giving patients a better chance at complete tumor eradication.
