a) Transverse angle maps and transmural transverse angle histograms of a midventricular slide. Gmax per channel is varied from 30 mT/m to 80 mT/m. Data reconstructed from only 4 signal averages of Gmax = 80 mT/m mimicking reduced SNR of the low Gmax acquisition is shown in right column. b) Signed mean differences and RMSE for sector wise analysis at apical, midventricular and basal level. The black boxes indicate the average over all sectors.
