Baby scanning - www.babyultrasound.co.uk
The method know as three dimensional ultrasound is used when a woman is in early pregnancy, it provides 3d pictures of the unborn baby. Most times the ultrasound images are quickly collected and combined to make a “4d ultrasound”.
Three dimensional scans works in the same manner to the normal scanning methods except that the ultrasound scanning waves can be directed from multiple directions. The ultrasound pulses are reflected back then captured to provide information to construct a 3 d image in very much the same way as 3d pictures. 3d ultrasound was devised in the usa.
It is important to understand that sonologists all over the world have always conjured 3d images of anatomy or pathology in their minds whilst doing 2d scans. However, until recently it was impossible to do this type of reconstruction on on information using ultrasound. With the introduction of baby scans for the first time allowed us a view into the brain of a sonologist and so letting us see the images on the ultrasound machine.
3d/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 non-medical situations should be undertaken with an understanding of the risks.
