The method know as 3d ultrasound is used in early pregnancy, it can provide 3d pictures of the unborn child. Most of the time these ultrasound samples are quickly collected and joined together to make a “4d ultrasound scan”.
Three dimensional scanning works in the same manner to the usual scanning methods except that the ultrasound waves can be directed from multiple directions. The ultrasound pulses are redirected back then captured to provide info to construct a 3d picture in in the same way as 3d pictures. 3d ultrasound was first developed by olaf von ramm and stephen smith in america.
It is important to understand that sonologists all over the world always conjured 3d pictures of the body in their minds while doing their 2d scans. However, until recently it was very difficult to do this type of reconstruction on on info using ultrasound. With the advent of 4d scans for the first time allowed us a peek into the brain of a sonologist and hence letting us view 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 medical situations should be undertaken with the understanding that a risk may exist.
