ABSTRACT
The trilogy of volume acquisition, manipulation, and display form the foundation for optimal image generation when employing three-dimensional (3D) ultrasound. Once a 3D volume is acquired, it may be displayed in the multiplanar mode. When rendering a volume, manipulation along the three axes may still be required for image optimization. In addition, the orientation from which to view the acquired volume may be altered by changing the direction of the region of interest. In surface rendering of the fetal face, a prerequisite is a good fluid interphase in front of the fetal face. The maximum mode is utilized to display the fetal skeleton – the ribs, spine, extremities, bony face, sutures of the fetal skull, or cranium. Tomographic ultrasound imaging is the sonographic equivalent of Computed tomography scanning. The trilogy of volume acquisition, manipulation, and display form the foundation for optimal image generation when employing 3D ultrasound.
