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

The method know as three dimensional ultrasound is used when a woman is in early pregnancy, it can provide 3d pictures of the unborn baby. Most times these ultrasound samples are collected and combined to produce a 4d scan.

Three dimensional scanning works similarly to the normal ultrasound methods except that the ultrasound scanning waves can be sent from multiple directions. The ultrasound waves are reflected back then captured to provide information to construct a 3d picture in in a similar manner to 3d movies. 3 dimesional ultasound scanning was started by stephen smith and olaf von ramm at duke university.

It is important to understand that sonologists all over the world have always pictured three-dimensional images of anatomy or pathology in their minds whilst doing 2d scans. However, until recently it was not possible to do this kind of reconstruction on on data using ultasound scanning. With the advent of 3d/ 4d ultrasound for the first time allowed us a peek into the mechanics of thinking of a sonologist and allowing us to reconstruct the images on the ultrasound machine.

The 3d/4d ultrasound image 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 should be undertaken with an understanding of the risks that may exist.
