Basics of Volume Acquisition<br />
Acquisition should attempt to overcome<br />
some of the inherent limitations of <strong>3D</strong> US:<br />
1. If there is acoustic shadowing in the acquisition<br />
plane it will be embedded in the volume<br />
2. If fetal movements are present during the<br />
acquisition; the result is motion artifacts<br />
3. If surface rendering is desired a fluid-tissue<br />
interface is needed<br />
4. Other factors such as fetal position and<br />
maternal obesity may challenge <strong>3D</strong> imaging just<br />
as in 2D
