Imaging processing, volumetric and cerebral surface reconstruction Axial (a), sagittal (b) and coronal (c) view of motion corrected and three dimensionally reconstructed brain of 29 weeks gestational age fetus with ventriculomegaly. Series of coronal section was manually segmented to regional structures (d). Axial (e), sagittal (f) and coronal (g) views of three-dimensional inner cortical plate surface reconstructed based on the same segmented images. Green and red color reflects positive and negative curvature values on the surface (green = gyri, red = sulci). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
