The Daily Mail has a write-up about multiple babies in the womb. They include 4D ultrasound and detailed silicone models. It was done for a National Geographic documentary. I hope I can get to see it!
The new 4D scan us ses the same frequency of sound waves w as in a normal ultrasound. But the sound waves are directed from many more angles, producing a 'real-time' video of the foetus as it moves and allowing scientists to say the images are in four dimensions.
This advanced technology has allowed scientists to capture the development of foetuses like never before, including twins and triplets jostling for space in the womb while grasping each other's hands and even faces.
Make sure you check out the slideshow. Amazing!
