Results of undersampled (R=48) verification experiments, plotting parameter map error $\left({\sigma }_{R_i}\right)$ per ROI as a function of the calculated aliasing noise quality factor $\left(1/\sqrt{q_i}\right)$ for the three tested sequences (θ_best, θ_average, and θ_worst). In (a), all data points are included achieving goodness of fit R²=0.89 and R²=0.20 in ${\sigma }_{R_1}$ and ${\sigma }_{R_2}$, respectively. In (b), obvious outliers from the ${\sigma }_{R_2}$ are excluded, resulting in goodness of fit R²=0.87.
