WDM i_Open 0.5T Open MRI System - Oncology Solutions

High-Field Open MRI Performance

Compared with standard permanent magnet open MRI systems operating at 0.3T or 0.4T, the 0.5T version delivers higher magnetic field strength, resulting in improved image clarity and shorter scan times. It features a 0.5 Tesla permanent magnet that eliminates the need for liquid helium, supporting helium-free operation and simplified system maintenance.

Permanent magnet: 0.5 Tesla field strength with helium-free operation
Open structure: U-shaped / dual-pillar design with an approximate 390 mm patient gap
Gradient system: Up to 30 mT/m with a slew rate of 100 mT/m/ms, enabling faster sequences and thinner slices
Reception channels: Digital hardware platform, typically with 4 independent channels, supporting phased-array coils for improved signal-to-noise ratio (SNR)

Technologies and Features

Fiber optic transmission: Uses digital RF fiber optic technology to minimize signal loss and reduce external electromagnetic interference
Advanced shimming: Passive and digital shimming technologies help maintain high magnetic field homogeneity within the scanning area
Scanning sequences: Includes a full range of clinical sequences such as SE, GE, IR, FSE, FGE, MRA, and STIR
Energy efficiency: Lower power consumption compared with superconducting systems, with no need for complex continuous cooling systems

Operational Advantages

No cooling-related maintenance costs: Since the system does not use liquid helium, there is no risk of quench and annual maintenance costs are significantly reduced
Simplified installation: Requires less space and does not need a dedicated quench pipe for helium evacuationogeneity within the scanning area
Improved patient comfort: The 300–320 degree open design significantly reduces patient anxiety and allows imaging of bariatric patients or those with special needs
