is a useful method for correcting the susceptibility-induced signal losses in
BOLD-EPI. For seeking the best z-shim images for compensating the lost
signal, an automatic real time z-shimming method was proposed in this study.
By implementing a feedback loop between the scanner and a PC through network
connection, the best z-shim value could be converged by the optimization
algorithm. In conclusion, our method not only can amend the signal losses
problem successfully but also provide rapider searching time and higher
accuracy of optimal z-shim value.
