About
Wellumio is a Wellington, New Zealand-based medical technology company developing Axana®, a portable, battery-powered brain imaging device for point-of-care stroke detection 123. The 50kg system uses proprietary Pulsed Gradient Free Mapping (PGFM) technology — patented in the U.S. in December 2025 — and requires no contrast agents, cryogenics, helium, or RF-shielded rooms, allowing deployment at the emergency room bedside 12. The company says PGFM has demonstrated clinical parity with conventional high-field MRI across key acute stroke biomarkers 12.
