Abstract: B0 field maps are used ubiquitously in neuroimaging, in disciplines ranging from magnetic resonance spectroscopy to temperature mapping and susceptibility‐weighted imaging. Most B0 maps are acquired using standard gradient‐echo–based vendor‐provided sequences, often comprised of two… read more here.
