June 1, 2007 – Clinicians at Edward Hospital in Naperville, IL, recently reported that they are using Trilogy, an image guided radiation therapy (IGRT) technology from Varian Medical Systems to offer some cancer patients a treatment that adapts to changes in the tumor so that more healthy tissue can be preserved.
This treatment is said to be helpful with the treatment of lung cancer, when breathing is already compromised and the doctor must spare as much healthy lung tissue as possible. Varian's Trilogy technology, equipped with an on-board imager device for generating 3-D CT images on the spot, reportedly made it possible to pinpoint the tumor each day, fine-tune patient positioning prior to treatment and see whether the tumor had shrunk enough to reduce the beam size and protect more of the healthy lung tissue.
