Reconstruction errors for the proposed method at different direct current (DC) thresholds

DC Threshold Non-DC 4%	VLA Mean ± SD	SA Mean ± SD	4ch Mean ± SD
1%	7.12 ± 2.85	4.60 ± 2.20	8.10 ± 1.98
4%	6.85 ± 2.73	4.46 ± 2.21	7.86 ± 1.77
10%	6.68 ± 2.64	4.46 ± 2.20	19.73 ± 3.43
30%	37.27 ± 18.12	4.46 ± 2.20	39.46 ± 8.70

The table reports the mean and SD for the errors of the proposed method at different DC thresholds calculated on the ROIs shown in Fig. 4 . Higher thresholds can increase the errors, and in all the cases considered, a 4% threshold is found to be an acceptable DC threshold. SA, short-axis; SD, standard deviation; VLA, vertical long-axis; 4ch, four-chamber.
