The method know as three dimensional ultrasound is used during early pregnancy, it can provide 3d pictures of the unborn baby. Most of the time these ultrasound images are collected and joined together and animated to make a 4d ultrasound scan.

Three dimensional scans works in a similar manner to the usual ultrasound methods except that the ultrasound pulses are directed from multiple directions. The ultrasound pulses are redirected back then captured to provide information to construct a 3d picture in in the same way as 3d pictures. 3 dimesional ultrasound was devised by olaf ramm abs stephen smith.

It’s important to understand that sonologists all over the world have always conjured 3d pictures of the body in their minds whilst doing 2d scans. However, until recently it was very difficult to do this type of reconstruction on on data using ultrasound. The advent of 4d scans for the first time allowed us a peek into the brain of a sonologist and allowing us to reconstruct the images on the ultrasound machine.

3d 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 an understanding of the risks involved.
