Trilogy® System from Varian® Medical Systems

Trilogy is a very flexible linear accelerator platform that uses Image Guided Radiation Therapy (IGRT) to deliver pinpoint radiation beam targeting and control, and shorter treatment sessions.

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 allowing your doctor to choose the right treatment for you.

The Trilogy 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 tumor. It 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. It also makes it an effective weapon against very small tumors.
