The method know as 3d ultrasound scanning is used when a woman is in early pregnancy, it can provide 3d pictures of the unborn child. Most of the time the ultrasound images are collected and joined together and made into a movie to make a 4d ultrasound scan.

Three dimensional scanning works in a similar manner to the normal ultrasound methods except that the ultrasound scanning pulses are directed from multiple directions. The waves can be reflected back then captured to provide information to construct a 3d image in in the same way as 3d movies. 3d ultrasound was devised in the usa.

It’s important to understand that sonologists all over the world always pictured 3d pictures of the body in their minds while carrying out 2d scans. However, until recently it was impossible to do this kind of reconstruction on on info using ultasound scanning. With the introduction of 4d baby scans for the first time allowed us a peek into the brain of a sonologist and so letting us see the images on the ultrasound machine.

3d/4d imaging should utilize ultrasound energy following the same limits as conventional 2d ultrasound to create the 3d images. There is no data to suggest harm due to 3d ultrasound, its use in none essential situations needs to be undertaken with the understanding of the risks.
