Asymmetric gradient coils introduce zeroth- and first-order concomitant field terms, in addition to higher-order terms common to both asymmetric and symmetric gradients. Salient to compensation strategies is the accurate calibration of the concomitan

BACKGROUND A low-cryogen, compact 3T (C3T) MRI scanner with high-performance gradients capable of simultaneously achieving 80 mT/m gradient amplitude and 700 T/m/second slew rate has been in use to study research patients since March 2016 but has not

The gradient coil (GC) is an essential component in MRI scanners as it provides linear Bz fields for spatial encoding. In advanced neuroimaging applications, head-only GCs have significant advantages over whole-body GCs. This is because the smaller G
