The results from this study that included cine SSFP images of the LV from 980 children show that LV volumes computed using commonly used bi-plane and tri-plane ellipsoidal models deviate significantly when compared to LV volumes estimated from a stack of short axis slices. A cut-cone+cone model of the LV proposed in this manuscript can estimate metrics describing LV function (EDV, ESV, and EF) with just two projections that are comparable to that obtained from an entire stack of short-axis slices.
