Cine fetal cardiac imaging with whole heart coverage presents numerous challenges due to maternal and fetal motion as well as high heart rate and lack of reliable independent synchronisation signal. To overcome these challenges, highly accelerated multi-slice 2D dynamic images were retrospectively reordered in time and aligned in space to produce a 3D cine using scattered interpolation methods with outlier rejection. The proposed methods were tested on ten human fetal subjects and validated using a numerical phantom.
