ViewRay, Inc. is a medical technology company specializing in the design, development and commercialization of magnetic resonance imaging (MRI)-guided radiation therapy systems for the treatment of cancer. Leveraging advanced MRI technology, the company’s platforms allow clinicians to visualize soft-tissue anatomy in real time, adapt treatment plans on the fly and deliver highly targeted radiation doses while minimizing exposure to surrounding healthy tissue. ViewRay’s core offering supports a range of treatment workflows, including intensity-modulated radiation therapy (IMRT) and stereotactic treatments, with applications across various cancer indications such as prostate, pancreas, liver and breast.
The flagship MRIdian system integrates onboard MRI with a radiation source engineered either from cobalt-60 or a linear accelerator, providing continuous imaging during radiation delivery. This real-time guidance enables automated gating, respiratory movement tracking and daily adaptive planning, enhancing precision and potentially improving patient outcomes. In addition to hardware sales, ViewRay provides comprehensive service contracts, software upgrades, clinical training and installation support through its global network of technical specialists and medical physicists.
Founded in 2004 and headquartered in Oakwood Village, Ohio, ViewRay achieved its first CE Mark in 2012 and U.S. Food and Drug Administration 510(k) clearance shortly thereafter. The company now serves more than 100 treatment centers worldwide, with regional offices and distribution partners across North America, Europe and the Asia-Pacific region. Collaborative research relationships with leading cancer institutes and academic centers help drive ongoing innovation, clinical evidence generation and expanded therapeutic applications.
Under the leadership of Founder and Chief Executive Officer Amir Homayoun, ViewRay continues to advance its product portfolio through ongoing R&D efforts in imaging enhancements, artificial intelligence-driven treatment planning and workflow automation. The management team’s combined expertise in medical imaging, oncology and systems engineering supports the company’s mission to redefine radiation therapy by improving the safety, efficacy and accessibility of cancer care globally.
