Dynamic distortion correction for improved EPI image quality in MRI
A novel MRI method dynamically correcting distortions in echo-planar imaging, addressing motion and field artifacts for high-quality, distortion-free images.
Applications: Magnetic Resonance Imaging (MRI)
| Features | Benefits |
|---|---|
| Simultaneously generate MRI magnitude images and off-resonance (field inhomogeneity) maps | Corrects off-resonance induced artefacts in EPI images, such as distortion and fat rings |
| Dynamic off-resonance mapping at high temporal rate | No field map acquisition required, reducing scan time |
| Single-shot multi-echo acquisition enabling Dixon-style water-fat separation | Corrects dynamic distortion changes caused by motion, respiration and scanner drift, enhancing image quality and precision |
| Highly robust to motion with single-shot acquisition | Highly robust against main magnetic field and transmit field inhomogeneity |
| Versatility Across Modalities | Reduced energy deposition and shorter scan time by eliminating the fat suppression pulse |
| Joint Multi-Echo image reconstruction | Maintains stability against physiological fluctuations with single-shot readout |
| Ensures reliable imaging even for subjects with significant motion and moving organs | |
| Applicable to any MRI modalities using an EPI readout, such as diffusion MRI, functional MRI and perfusion MRI | |
| Ensure comparable data quality as conventional EPI, while providing additional off-resonance information |
