Results of autoQSM, TKD and iLSQR for QSM reconstruction on the brain numerical phantom susceptibility model as well as the difference with respect to the ground truth. The input is the masked total phase map from a simulated background field superimposed onto the simulated brain phantom. Compared to TKD and iLSQR, autoQSM delivers substantially lower error level. (a) true tissue magnetic susceptibility; (b) simulated total phase image; (c-e) reconstructed QSM images using autoQSM, TKD and iLSQR, respectively; (f-h) the difference maps of autoQSM, TKD and iLSQR with respect to the true magnetic susceptibility map.
