Comparison between the OEF obtained by QQ without and with CAT at different SNRs in the simulated stroke brain (Numerical Simulation 2). At all SNRs, QQ with CAT captures low OEF values, whereas QQ without CAT is not sensitive to low OEF values at low SNRs. The numbers in white indicate the OEF average and standard deviation in the whole brain, and black represents the root-mean-square error (RMSE).
