4D Reconstruction of Fetal Heart Ultrasound Images in Presence of Fetal Motion
4D ultrasound imaging of the fetal heart relies on reconstructions from B-mode images. In the presence of fetal or mother’s motion, current approaches suffer from artifacts. We propose to use many sweeps and exploit the resulting redundancy to recover from motion by reconstructing a 4D image which is consistent in phase, space and time. We first quantified the performance of 7 formulations on simulated data. Reconstructions of the best and baseline approach were then visually compared for 10 in-vivo sequences. Ratings from 4 observers showed that the proposed consistent reconstruction significantly improved image quality.
