AI Technical Summary
Technical Problem
Magnetic resonance imaging systems face challenges with magnetization and chemical shift artifacts, spatial distortions, and reduced signal-to-noise ratio at low magnetic field strengths, limiting diagnostic and intervention applications.
Method used
The system employs low magnetic field strengths (≤1.0 Tesla), high gradient coil intensities, large flip angles, and sparse sampling imaging technology to minimize artifacts and maintain high frame rates, enabling high-quality MRI with reduced chemical shift and magnetic sensitivity.
Benefits of technology
This approach achieves high spatial consistency and signal-to-noise ratio, supporting accurate diagnostics and interventions with real-time 2D and 3D MRI guidance, reducing patient heating and ionizing radiation exposure.
