Ultrasound is high frequency sound waves that are out of the range of human hearing.
Your baby is unaware and unaffected by these high frequency sound waves.
Ultrasound does not use radiation or x-rays to create images.
2D ultrasound has been in use in the UK and the rest of the world for more than 30 years.
3D and 4D Ultrasound scans are no different from 2D ultrasound scans.
The new ultrasound technology uses identical sound waves as 2D but new advances in transducer and computer technology allow the ultrasound signal to be viewed in 3D or 4D (4D is 3 dimensions with movement).
Our GE Voluson pro ultrasound machine is one of the best in its field, and is fully maintained by GE Medical.
