Narrator: This is Science Today. While three-dimensional ultrasound is not exactly a new concept, advanced computer technology is making 3D-ultrasound an exciting tool in the field of obstetrics. Thomas Nelson, a professor of radiology at the University of California, San Diego, says with this technology, expectant parents can get an almost picture-perfect view of their baby.
Nelson: This makes it very easy to convey information about what is actually taking place in the level of development of the child in a way that we've never been able to do before. And because it's non-invasive and painless and very rapid, it makes it much easier for us to one, understand what's going on and two, can share that with the patient and that' s, I think, one of the real big advantages.
Narrator: With the current two-dimensional ultrasound, Nelson says it takes a very trained and skilled eye to sort out if the development is normal since the pictures are not always very clear.
Nelson: With 3D-ultrasound, it's much easier to differentiate those things and so we can identify normal development of the baby with a higher degree of accuracy.
