ViewRay's MRIdian System Featured at AAPM 2015

Users presented on online adaptive and real-time motion tracking with MRI-guided radiation therapy

July 22, 2015 - ViewRay's MRIdian System, the world's first and only magnetic resonance imaging (MRI)-guided radiation therapy system, was featured during the 2015 annual meeting of the American Association of Physicists in Medicine (AAPM). This year's meeting was held July 12-16 in Anaheim, California.

The MRIdian System is designed to improve the accuracy of cancer treatments through a patented combination of simultaneous MRI and radiation therapy delivery. With continuous soft-tissue imaging, clinicians can clearly see the cancer target, monitor where the actual radiation dose is being delivered, and adapt to changes in the patient's anatomy – all in real time while the patient is on the treatment table. This provides a more precise and personalized cancer treatment.

AAPM selected 20 abstracts reporting on real-world clinical experience with MR-guided radiation therapy from three MRIdian sites. These oral and poster presentations included the "Best in Physics" presentation: An Integrated Model-Based Intrafractional Organ Motion Tracking Approach with Dynamic MRI in Head and Neck Radiotherapy. The presentations covered a wide range of topics including on-table adaptive treatments, real-time MR motion tracking, online Monte Carlo dose calculations and several relating to system quality assurance.

Additionally, a number of physicist users of the MRIdian System presented on their experience in ViewRay's booth. Clinical applications experts from ViewRay were also available in the booth to demonstrate treatment planning and delivery functionality of the system.
