The method know as 3d ultrasound is used during early pregnancy, it can provide 3d pictures of the fetus. Most times these ultrasound pictures are collated and joined together to produce a “4d ultrasound”.

Three dimensional scans works in a similar manner to the normal ultrasound methods except that the ultrasound pulses can be directed from multiple directions. The waves can be reflected back and captured and provide information to construct a 3d picture in much the same way as 3d pictures. 3d ultasound scanning was first developed by olaf von ramm and stephen smith in america.

It’s important to understand that sonologists all over the world always pictured 3d images of anatomy or pathology in their minds while doing 2d scans. However, until recently it was not possible to do this kind of reconstruction on on patient information using ultasound scanning. With the introduction of 4d baby scans for the first time allowed us a peek into the mechanics of thinking of a sonologist and so allowing us see the images on the ultrasound machine.

4d ultrasound 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 ultasound scanning, its use in none essential situations needs to be undertaken with an understanding of the risks involved.
