Measurements Using NMR Imaging Systems TRIZ Cases
- MRI ROI Position Correction for Chemical Shift Alignment
Chemical-shift-based ROI correction aligns MRI spectroscopy target regions with metabolites, improving spectral analysis and diagnosis accuracy.
- Non-Localized RF Shimming for Uniform Parallel MRI Transmission
A non-localized RF shim penalizes under-flipping to improve B1+ uniformity, reduce signal dropout, and maintain transmit efficiency in parallel MRI.
- bSSFP MRI Phase Alignment for White-Marker Interface Artifacts
Phase tuning in bSSFP MRI suppresses white-marker signal boosts at fat-water interfaces while preserving visibility near magnetic-field-changing objects.
- AI-Generated MRI Media Playback Matched to Scan Noise and Duration
Generative AI tailors MRI audio or video to scan timing and gradient noise, easing patient stress and reducing motion artifacts.
- MRI Gradient Coil Prescan for Center Frequency Drift Correction
Prescan temperature and frequency data across X, Y, and Z gradient coils enables center frequency correction and clearer MRI fat suppression.
