Elimination of hardware artifacts at low field MRI (6.5 mT) using AUTOMAP. Two slices from a 3D bSSFP (NA = 50) are shown. When reconstructed with IFFT (a, b), a vertical artifact (red arrows) is present across slices. When the same raw data was reconstructed with AUTOMAP (c, d), the artifacts are eliminated. The error maps of each slice with respect to a reference scan (NA = 100) is shown for both IFFT and AUTOMAP reconstruction. e–g Uncorrupted k-space (NA = 50) was reconstructed with AUTOMAP (e) and IFFT (f).
