RapidArc® is a technology we use in our Trilogy® system to deliver intensity modulated radiation therapy (IMRT) with speed and precision.

With RapidArc, doctors use computer-generated images to plan and deliver the radiation dose. In one or more arc treatments, a linear accelerator revolves around the patient, delivering a sculpted, tightly-focused beam of radiation directly to a tumor in less than two minutes, which is much faster than traditional IMRT.

During treatment, the beam is continually shaped and modulated to conform to the shape of the tumor. Treatment can also be delivered from nearly any angle.

This may result in better tumor targeting and less damage to surrounding healthy tissue. It also may reduce the amount of time a patient spends in radiation treatment, which is usually administered five days a week for several weeks.
