Vision RT Ltd

What Vision RT Ltd does

Vision RT Ltd., founded in 2001 and headquartered in London, is the named inventor and market leader in Surface Guided Radiation Therapy (SGRT). The company develops camera-based 3D surface imaging systems that track patient positioning and motion in real time during radiotherapy. Its product architecture spans the full radiotherapy workflow: SimRT for 4D and breath-hold CT simulation, MapRT for clearance mapping during treatment planning, AlignRT (including AlignRT InBore) for motion management at the treatment console, and DoseRT for real-time Cherenkov-based dose verification, supported by an extensive module catalog (Auto ROI, Beam Guide, Postural Video, OIS Reports, Respiratory, Stereotactic, Patient ID, Real Time Coach Display, PatientSide, and Head Adjusters). Over 3,000 systems are in active clinical use globally, including at 24 of the top 25 US cancer hospitals, with 300+ peer-reviewed publications validating clinical outcomes.

The company sells directly to oncology clinics, cancer centers, teaching hospitals, and radiotherapy departments via an enterprise field sales motion with clinical application support. Pricing is quote-based and structured as multi-year contracts covering hardware, software, and ongoing support; the Mix includes one-time system revenue plus a growing recurring subscription and services layer. Distribution is supported by regional offices in the United States (North America headquarters), Warsaw (Europe), Delhi (Asia-Pacific), Dubai (Middle East), and Melbourne (Australasia), with a global headcount approaching 400. Strategic alliances with radiotherapy OEM Accuray (AlignRT InBore on the Helical Platform) and treatment planning vendor RaySearch Laboratories position the technology inside the broader linac + TPS stack.

Vision RT is privately held and operates within the William Demant Invest (WDI) family, a Danish Medtech investor with a long-term investment orientation and more than 21,000 employees across its broader portfolio. The company has received the King's Award for Enterprise (2024) and was named to The Sunday Times 100 Tech list in both 2025 and 2026.
