Normalized root mean squared error (NRMSE) between SR reconstructions from simulated data at a GA of 26, 30 and 33 weeks respectively and the corresponding 3D HR ground truth depending on the weight \(\lambda\) of the TV regularization. Six values of \(\lambda\) are tested: 0.1, 0.3, 0.5, 0.75, 1.5 and 3. The NRMSE is minimal for \(\lambda\) = 0.75.
