I've just come upon a fascinating online exhibition from Cambridge University tracing the ways in which embryos and foetuses have been visualised through history. This is what I wrote my Master's thesis about, particularly trying to understand what it means to look at foetuses in 3D today.
Also have a look at A Short History of Ultrasound in Obstetrics and Gynecology if you're keen!
Anyone out there looking to have a 3D ultrasound? Had one already?
