4d scans allowing you to see your baby in the womb

The method know as three dimensional ultrasound scanning is used when a woman is in early pregnancy, it provides 3d images of the fetus. Most of the time these ultrasound samples are collated and joined together and animated to produce a 4d scan.

Three dimensional scanning works similarly to the normal ultrasound scanning methods except that the ultrasound scanning waves can be sent from multiple directions. The waves are redirected back and captured and provide information to construct a 3-dimensional picture in in a similar manner to 3d pictures. 3 dimesional ultrasound was devised by olaf ramm and stephen smith.

It's important to understand that sonologists around the world have always conjured 3d pictures of the body in their minds while doing 2d scans. However, until recently it was difficult to do this kind of reconstruction on on patient information using ultrasound. With the advent of 3d/ 4d ultrasound for the first time allowed us a view into the brain of a sonologist and so allowing us see the images on the ultrasound machine.

3d/4d ultrasound imaging should utilize ultrasound energy following the same limits as conventional 2d ultrasound to create the 3d images. While there is no information of harm due to 3d ultasound scanning, its use in none essential situations should be undertaken with an understanding of the risks that may exist.
