A crowded womb: 4D Ultrasound
The future of prenatal screening belongs to the 4D scan. It uses the same frequency of sound waves as a normal ultrasound, but the sound waves are directed from many more angles, producing a ‘real-time’ video of the foetus.
London-based obstetrician Professor Stuart Campbell, who is the pioneer of 4D scans in Britain, performed the scans for a National Geographic documentary.
He says: ‘It was fascinating to see the babies in more detail than ever before. I was amazed at the detail in the faces – smiles, blinking – and the interaction between multiple foetuses.’
