The method know as three dimensional ultrasound scanning is used during early pregnancy, it provides 3d images of the unborn child. Most of the time the ultrasound pictures are quickly collected and combined and animated to make a “4d ultrasound scan”.

Three dimensional scans works similarly to the usual scanning methods except that the ultrasound pulses can be directed from multiple directions. The ultrasound waves are reflected back then captured to provide information to construct a 3-dimensional picture in in the same way as 3d movies. 3d ultasound scanning was devised by olaf ramm abs stephen smith.

It’s important to understand that sonologists all over the world always conjured 3d pictures of the body in their minds while carrying out 2d scans. However, until recently it was difficult to do this kind of reconstruction on on information using ultasound scanning. With the advent of ultrasound baby scans 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.

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 harm due to 3d ultrasound, its use in none medical situations should be undertaken with an understanding of the risks that may exist.
