Hitachi Airis II
Family: Hitachi Airis · Modality: Open / Extremity MRI
Open-architecture 0.3T permanent-magnet MRI — designed for claustrophobic patients, interventional access, and pediatric imaging. Permanent-magnet design eliminates helium / cryo service burden but at the cost of image quality vs mid-to-high-field systems. Large community outpatient install base.
Variant-specific considerations
- 0.3T permanent magnet — no cryogens, no helium refills, no quench risk
- Open C-shaped gantry with wide patient access
- Image quality sits between 0.2T scanners and 1.0T; sufficient for MSK, routine brain, some body
- No helium-service business model; mechanical maintenance dominates
Parts
Permanent magnet assembly, gradient coil, RF chain, patient table.
Successors / siblings
- Hitachi Airis Elite, Airis Vento — higher-performance extremity / open variants
- Esaote O-Scan (extremity-only competitor)
