Since 2017, Oxipit has been building radiology AI you can trust—tools that analyze chest X-rays, support faster diagnoses, and ease the workload for clinical teams. As imaging volumes rise and pressure on radiology departments grows, our mission is clear: reduce the burden, support precision, and help radiologists focus on what matters most. Oxipits CXR Suite is a certified, powerful portfolio of radiology AI tools designed to streamline chest X-ray diagnostics from start to finish. Trusted by healthcare institutions globally, the CXR Suite brings together three advanced solutions: • ChestLink – the world’s first autonomous AI for normal chest X-rays, safely removing up to 40% of studies from radiologists’ workloads with 99.9% sensitivity. • ChestEye – an on-screen assistant that detects 75 findings, supporting diagnostic quality and day-to-day decision-making. • ChestQuality – a second set of eyes—continuously reviewing reports to support accuracy and catch overlooked findings. No matter where you are in your AI journey, the Oxipit CXR Suite meets you there. Start with the tools that fit your needs today—and scale as your workflow evolves. The future of radiology AI is flexible—and autonomous.
