4d Baby Scans

The method know as 3d ultrasound scanning is that can be used during early pregnancy, providing 3 d pictures of the fetus. Most of the time these ultrasound pictures are rapidly collected and joined together and animated to make a "4d ultrasound scan".

Three dimensional scanning works in the same manner to the normal ultrasound methods except that the ultrasound waves are sent from multiple directions. The ultrasound pulses are reflected back then captured to provide information to construct a 3d picture in very much the same way as 3d movies. 3d ultrasound was started by stephen smith and olaf von ramm at duke university.

It's important to understand that sonologists worldwide have always conjured 3d images of anatomy or pathology in their minds while doing their 2d scans. However, until recently it was not possible to do this kind of reconstruction on on info using ultrasound. With the introduction of 3d/4d ultrasound for the first time allowed us a view into the thinking of a sonologist and hence letting 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 ultrasound, its use in non-medical situations should be undertaken with the understanding that a risk may exist.
