Trilogy System
Trilogy™ System Offers New Treatment Options“Image-Guided” Focus on Tumors Near the Spinal Cord
The System provides highly focused, “image-guided” radiotherapy and radiosurgery options for treating tumors and other lesions located close to the spinal cord or other critical structures. It may be used alone or in combination with surgery, depending on a tumor’s location and type.
Using a specialized CT scanner built into the treatment planning machine, Trilogy™ ensures that a radiation dose precisely hits its target. Among other features is a “respiratory gating” capability that can take a patient’s breathing into account and time delivery of radiation accordingly.
Image-guided radiotherapy allows precisely focused radiation, reducing considerably the size of a treatment field. Radiation is delivered through multiple “arcs,” minimizing radiation exposure to surrounding tissue, while intensifying dosage at the point of intersection.
Trilogy is a “frameless” system able to precisely treat lesions in areas of the body that are not easily immobilized. It adds another dimension to Cedars-Sinai’s radiation therapy arsenal, which includes the Gamma Knife® Center. Each system has its strengths and offers advantages in certain situations. The Gamma Knife, which uses a frame to immobilize the head, is the first choice for most tumors and other lesions in the brain.
