Description
Xu and co-authors automate magnetic field smoothing for brain scans in a 2023 paper. Uneven fields bend images and blur spectra, above all at high field strength. Hand-picked regions make older high-order fixes slow and subjective. Their method lets a learning model cut out the brain on its own, then runs image-based shimming on that region in real time.
Tests at two field strengths, with picture and spectra scans, beat both basic and hand-guided high-order shimming. Image warping shrank and spectral lines narrowed. No user steps remain in the loop. The authors offer the method for busy imaging centers that need steady quality.
