CLEVELAND, July 28, 2016 /PRNewswire/ -- ViewRay, Inc. (Nasdaq: VRAY), makers of the world's first and only clinical MRI-guided radiation therapy system, announced today that the company's MRIdian® System is the focus of 40 abstracts selected by the American Association of Physicists in Medicine (AAPM) for presentation during their 2016 Annual Meeting. AAPM is the largest association of medical physicists in the world and this year's meeting will be held July 31-August 4 in Washington, DC.

The MRIdian-based presentations, which include talks, posters and e-posters, will highlight topics such as adaptive radiotherapy, margin reduction, dosimetric accuracy and functional MRI for response assessment. These include experience across various clinical indications including sarcoma, lymphoma and cancers of the esophagus, pancreas, brain, lung, head and neck. Abstracts accepted by AAPM were provided by MRIdian users at five different centers: Washington University in St. Louis, Mo.; University of Wisconsin in Madison, Wis.; University of California, Los Angeles, Calif.; Seoul National University Hospital in Seoul in South Korea; and University of Miami in Miami, Fla.

Seven of this year's presentations focus specifically on MRIdian's on-table adaptive capabilities. These include two clinical studies presented by the University of Wisconsin, Madison that examine interfraction changes to illustrate the importance of on-table adaptation: one study evaluates interfraction variations in stomach deformation in gastric cancer patients, and a second study measures day-to-day changes in the distance between the pancreas and duodenum in pancreatic cancer patients. Another study from the University of Wisconsin explores MRIdian's ability to perform a single session where the patient is simulated, adapted on-table, and treated, all within 30 minutes, leveraging the system's in-room soft tissue imaging, fast auto-contouring and treatment re-planning tools.
Researchers from Washington University School of Medicine, who have been using MRIdian for adaptive therapy in patients since September 2014, will present on how to implement on-table adaptive treatments in a clinical environment and the potential role of real-time MRI-guided motion management for SBRT.

Additionally, in ViewRay's booth #5045, MRIdian users from University of California, Los Angeles; University of Miami; Washington University in St. Louis, Mo.; and University of Wisconsin in Madison, Wis., will present on their firsthand experience. Topics to be addressed include MR-IGRT implementation, gating and motion management, clinical experience and patient case studies across various indications, SBRT delivery, and use of on-table adaptive capabilities.
