The method know as three dimensional ultrasound is used in early pregnancy, it provides 3d images of the fetus. Most of the time these ultrasound images are rapidly collected and combined to created a 4d scan.

Three dimensional scans works similarly to the normal ultrasound methods except that the ultrasound pulses are sent from many directions. The ultrasound pulses can be reflected back and captured and provide information to construct a 3d image in much the same way as 3d movies. 3d ultasound scanning was started by stephen smith and olaf von ramm.

It’s important to understand that sonologists everywhere always pictured three-dimensional images of anatomy or pathology in their minds while carrying out 2d scans. However, until recently it was very difficult to do this type of reconstruction on on information using ultasound scanning. With the advent of baby scans for the first time allowed us a view into the thinking of a sonologist and so allowing us see 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. While there is no information of harm due to 3d ultasound scanning, its use in none medical situations should be undertaken with an understanding of the risks that exist.
