It’s important to understand that sonologists all over the world have always pictured three-dimensional images of anatomy or pathology in their minds while carrying out 2d scans. However, until recently it was impossible to do this type of reconstruction on on info using ultasound scanning. With the advent of ultrasound baby scans for the first time allowed us a peek into the mechanics of thinking of a sonologist and so allowing us see the images on the ultrasound machine.

4d ultrasound imaging should utilize ultrasound energy following the same limits as conventional 2d ultrasound to create the 3d images. There is no data to suggest any harm due to 3d ultasound scanning, its use in non-medical situations should be undertaken with the understanding of the risks.
