4d baby scans - babyultrasound.co.uk
The method know as 3d ultrasound is that can be used when a woman is in early pregnancy, providing 3 d pictures of the fetus. Most times the ultrasound samples are collated and joined together and animated to produce a 4d scan.
Three dimensional scans works in the same manner to the normal ultrasound scanning methods except that the ultrasound scanning waves are directed from multiple directions. The ultrasound pulses are redirected back and captured and provide information to construct a 3d picture in in the same way as 3d movies. 3d ultasound scanning was devised by olaf ramm abs stephen smith.
It is important to understand that sonologists all over the world have always pictured 3d pictures of anatomy or pathology in their minds while carrying out 2d scans. However, until recently it was difficult to do this kind of reconstruction on on information using ultasound scanning. The advent of 4d baby 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.
3d/4d ultrasound 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 non-medical situations needs to be undertaken with the understanding of the risks.
