Baby scanning - www.babyultrasound.co.uk
The method know as 3d ultrasound is used during early pregnancy, it provides 3d images of the unborn baby. Most times these ultrasound images are quickly collected and combined to produce a 4d scan.
Three dimensional scanning works in the same way to the normal scanning methods except that the ultrasound waves are sent from multiple directions. The ultrasound pulses can be reflected back then captured to provide information to construct a 3 d picture in in the same way as 3d pictures. 3 dimesional ultasound scanning was first developed by olaf von ramm and stephen smith in america.
It is important to understand that sonologists all over the world have always conjured 3d images 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 ultasound scanning. With the advent of baby scans for the first time allowed us a view into the thinking of a sonologist and hence 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 ultasound scanning, its use in none medical situations needs to be undertaken with the understanding of the risks.
