Soft-tissue Targeting, ViewRay System and Margaret's Story
With ViewRay’s MRI-guided IMRT system, up to three soft-tissue imaging planes can be captured continuously during treatment without exposing the patient to unnecessary ionizing radiation.
If the tumor or a critical structure moves beyond a physician-defined boundary, the treatment beam automatically pauses; when the structure moves back into the target zone, treatment automatically resumes. Physicians can set both spatial and time thresholds for pausing treatment delivery, controlling for the motion of a patient’s organs based on real-time 4D MRI data.
The ViewRay system is designed to watch a tumor and adjust for its movement in real time. Continuous tracking of soft tissue and automatic beam gating provide safe and accurate targeting during treatment.
The ViewRay™ system uses a unique combination of magnetic resonance imaging (MRI) and radiation therapy technology to provide high-contrast pretreatment images and continuous soft-tissue imaging during treatment. Prior to treatment, MR imaging improves patient positioning in conventional timeframes. During beam-on irradiation, the system captures a stream of softtissue images and acts on them—at subsecond speed—to provide greater assurance that the treatment delivered is precisely the treatment prescribed.
