The method know as three dimensional ultrasound is used during early pregnancy, it can provide 3d pictures of the unborn baby. Most times these pictures are captured and combined and animated to produce a “4d ultrasound”.

Three dimensional scans works in a similar way to the traditional ultrasound except that the ultrasound pulses can be sent from multiple directions. The ultrasound waves can be reflected back and captured and provide information to construct a 3d picture in in the same way as 3d movies. 3 dimesional ultasound scanning was devised in the usa.

It is important to understand that sonologists around the world have always conjured 3d images of anatomy or pathology in their minds while carrying out 2d scans. However, until recently it was very difficult to do this kind of reconstruction on on patient information using ultrasound. With the advent of 4d baby scans for the first time allowed us a peek into the 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. While there is no information of harm due to 3d ultrasound, its use in none essential situations should be undertaken with the understanding of the risks.
