Bloch-McConnell equation based digital phantom studies using simulated B₀ and B₁ errors. Four digital phantoms (PH1, PH2, PH3, and PH4) and the MRF schedule optimized with the learning-based optimization of acquisition schedule (LOAS) were used to simulate MTC-MRF images. Three fingerprints (red, black and blue) encode the same tissue parameters but with different saturation powers due to rB1. The simulated fingerprints and scan parameters (${\text{p}}_{\text{scan}}^{\text{nom}}$ or ${\text{p}}_{\text{scan}}^{\text{corr}}$) were fed to the trained RNN to quantify the tissue parameters.
