Fig. 2From: Fetal XCMR: a numerical phantom for fetal cardiovascular magnetic resonance imagingExample motion states using the Fetal XCMR phantom. Fetal XCMR images in a short-axis orientation (a) were generated over multiple timepoints to illustrate the temporal dynamics (M-mode) along the dashed-line in (a) for a simulated maternal breath-hold (b) demonstrating only fetal cardiac motion, a simulated free-breathing acquisition (c) demonstrating both maternal respiration and fetal cardiac motion, and a free-breathing acquisition with gross fetal movement (d) demonstrating three independent motionsBack to article page
