ViewRay - MR Imaging and Soft-Tissue Targeting

True image-guided radiation therapy

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.

ViewRay

On-table dose prediction and optimization

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.

A specialized radiation therapy system
A purpose-built imaging and radiation therapy device, the ViewRay system has the potential to improve the accuracy of both pretreatment setups and treatment delivery. The ViewRay system’s patented design uses an MR imager engineered specifically for interventional radiation therapy procedures. The system’s MRI component features a custom-designed split gradient coil with three-axis cooling and a split 0.35T magnet designed to enable continuous imaging. With a radiation therapy gantry placed between a split magnet and gradient coil, MR imaging and treatment delivery can occur simultaneously, for true image-guided radiation therapy.

Tools for dose prediction, optimization, and assessment
The ViewRay™ radiation therapy system provides sophisticated decision-support tools to help clinicians understand, manage, and refine dose delivery throughout the treatment process.

The ViewRay system gathers data from all points in the radiation therapy process—the physician-prescribed treatment plan, pretreatment images, and soft-tissue images and motion data captured during therapy—and gives clinicians the means to apply that wealth of data. On-table dose prediction tools use volumetric image data captured just prior to treatment to ensure accurate positioning. Reoptimization capabilities enable smooth adjustments while the patient is still on the treatment table. And review and assessment tools give physicians the detailed dose and motion information they need to adapt treatments between fractions.

With MRI guidance and a suite of tools for fine-tuning prescriptions, the ViewRay system provides a fresh approach to observing, assessing, and personalizing a patient’s treatment.

ViewRay program at UCLA offers groundbreaking treatment for cancer patients.
