Table containing scan parameters for fully-sampled training and prospective data collection. All training datasets were acquired from 22 healthy volunteers using a fully-sampled cine acquisition (R=1). Two datasets were acquired from each pediatric patient with 2-fold uniformly undersampled cine acquisition (R=2), and 12-fold k-t undersampled cine acquisition (R=12).

^*For fully-sampled training data, the number of slices varied depending on the scan plane. Ten to twelve slices were acquired in short-axis views, while only one to three slices were acquired for long-axis views.

^**Reported scan times do not include resting periods between breath-holds.
