What ViewRay does
ViewRay Systems, Inc. designs, manufactures, and sells the MRIdian A3i, an MRI-guided radiation therapy system that integrates diagnostic-quality MRI imaging with real-time radiation delivery in a single platform. The company's core technology combines high-field MRI for soft-tissue visualization with automated beam gating and tissue tracking, enabling clinicians to deliver ablative radiation doses with greater precision than conventional radiotherapy systems that rely on implanted markers. The system is positioned for the treatment of pancreatic, prostate, lung, liver, breast, and oligometastatic cancers.
The company sells its systems directly to hospitals and cancer treatment centers worldwide through an enterprise field sales motion, supplemented by clinical webinars, scientific presentations, and patient advocacy content targeting radiation oncologists. Revenue is generated primarily through capital equipment sales of the MRIdian A3i system, with an overlaid recurring service and support revenue stream managed through a dedicated customer portal. Founded in 2004 and headquartered in Oakwood Village, Ohio, ViewRay has raised approximately $700 million+ in cumulative equity and debt financing across multiple rounds since 2008, with the most recent being a $125 million debt facility from MidCap Financial and Silicon Valley Bank in November 2022. The radiotherapy market in which ViewRay operates was approximately $10.2 billion in 2024 and is projected to grow at a 4.2% CAGR to $12.5 billion by 2029, against larger competitors including Elekta, Siemens Healthineers, GE HealthCare, Canon Medical Systems, and Accuray.
