Fully-Automated Alignment of 3D Fetal Brain Ultrasound to a Canonical Reference Space using Multi-Task Learning

Fetal neurosonography has improved significantly in the last few decades. It is emerging as a clinically useful imaging technology for assessing brain development and detecting cerebral abnormalities in the womb, which has applications in settings where expensive magnetic resonance imaging (MRI) is unavailable or not well-suited. Regardless of imaging modality, fetal brain localization and geometric alignment are the primordial steps for neuroimage analysis. This analysis relies on (i) initial localization of the brain, (ii) removal of extracranial and maternal tissues, and (iii) alignment of the region of interest to a referential coordinate system (reference space).
