The method know as three dimensional ultrasound is used during early pregnancy, it provides 3d pictures of the fetus. Most times the ultrasound images are quickly collected and combined to created a 4d ultrasound scan.

Three dimensional scans works in the same manner to the normal ultrasound methods except that the ultrasound scanning pulses can be sent from many directions. The waves can be redirected back and captured and provide information to construct a 3d picture in very much the same way as 3d pictures. 3 dimesional ultrasound was devised by olaf ramm and stephen smith.

It’s important to understand that sonologists all over the world always conjured 3d images of the body 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 4d baby scans for the first time allowed us a peek into the thinking of a sonologist and so letting 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 any harm due to 3d ultrasound, its use in none medical situations needs to be undertaken with an understanding of the risks involved.
