The Trilogy™ Stereotactic System from Varian Medical Systems
OVERVIEW
 The Trilogy™ Stereotactic System from Varian Medical Systems is the most
advanced, sophisticated machine of its type in the world.
As the leading image-guided radiotherapy (IGRT) system, Trilogy marks the beginning
of a new generation of cancer care. The versatile Trilogy system combines imaging
and treatment technologies, and can be used to deliver the widest range of external
beam radiotherapies: 3D conformal radiotherapy, IMRT, stereotactic radiosurgery,
fractionated stereotactic radiation therapy and intensity-modulated radiosurgery
for cancer and neurosurgical treatments.
Advanced imaging capabilities built into the system allow therapists to position
patients for treatment with submillimeter accuracy. A respiratory gating system
compensates for any tumor movement that occurs as a patient breathes.
The Trilogy system is powerful, and it can deliver radiotherapy doses at least
60 percent faster than conventional accelerators. This shortens the length of
time patients need to spend undergoing treatment. In addition, the radiation beam
is highly precise, allowing clinicians to deliver treatments with unprecedented
accuracy.
