ABSTRACT
Surface rendering of the fetus from three-dimensional (3-D) volume sets was first reported by Baba and Sato in the mid-1980s (Figs. 1 and 2) (1). This was followed by reconstruction of a 3-D volume set as three orthogonal sections in the early 1990s (Fig. 3) (2). Widespread usage of the 3-D technique was initially hindered by the very slow processing speeds of the computers used to coordinate the reconstruction of the visual sections and by the need for these computer work stations to be separate from the ultrasound machine.
