Abstract
Pre-term neonates born with a low birth weight (<1500g) are at increased risk for developing intraventricular hemorrhage (IVH). 3D ultrasound (US) imaging has been used to quantitatively monitor the ventricular volume in IVH neonates, instead of typical 2D US used clinically, which relies on linear measurements from a single slice and visually estimates to determine ventricular dilation. To translate 3D US imaging into clinical setting, an accurate segmentation algorithm would be desirable to automatically extract the ventricular system from 3D US images. In this paper, we propose an automatic multi-region segmentation approach for delineating lateral ventricles of pre-term neonates from 3D US images, which makes use of multi-phase geodesic level-sets (MP-GLS) segmentation technique via a variational region competition principle and a spatial shape prior derived from pre-segmented atlases. Experimental results using 15 IVH patient images show that the proposed GPU-implemented approach is accurate in terms of the Dice similarity coefficient (DSC), the mean absolute surface distance (MAD), and maximum absolute surface distance (MAXD). To the best of our knowledge, this paper reports the first study on automatic segmentation of ventricular system of premature neonatal brains from 3D US images.
