Ultrasound scans have been a commonplace part of pre-natal care for several decades, since they were introduced into the field by Professor Ian MacDonald in the 1960s.
Although useful, many of these scratchy, two-dimensional images have relied heavily on the willing imagination of the prospective parents to make out shapes and forms resembling a baby.
Today, thanks to the latest state-of-the-art 3D and 4D ultrasound scanning equipment, parents can see their unborn baby in incredible detail, revealing facial features, expressions, and even movement, from as early as 12 weeks.
This article on 3D and 4D Ultrasound Scans is written by Jackie Griffiths, a freelance journalist who writes health, medical, biological, and pharmaceutical articles for national and international journals, newsletters and web sites.
