In clinical 3T imaging, gradient-echo-based sequences
oftensuffer from signal loss induced by patient specific
susceptibility artifacts. To tackle this problem, a
recently proposed local signal recovery method using
parallel transmission was transferred to a clinical
setup. The approach was further extended by B1
inhomogeneity correction and evaluated with human
in-vivo experiments using the common FLASH sequence.
Signals could be recovered up to 50% in frontal orbital
cortex, while maintaining the SNR level. Full signal
recovery could be achieved, if lower SNR levels are
tolerated.
