4d scans - baby ultrasound.co.uk
The method know as three dimensional ultrasound scanning is that can be used during early pregnancy, it provides 3d pictures of the unborn baby. Most of the time these ultrasound pictures are captured and joined together and made into a movie to produce a “4d ultrasound scan”.
Three dimensional scans works similarly to the normal ultrasound scanning methods except that the ultrasound scanning pulses are sent from many directions. The waves can be reflected back then captured to provide info to construct a 3d picture in much the same way as 3d movies. 3d ultrasound was started by stephen smith and olaf von ramm.
It’s important to understand that sonologists all over the world have always pictured 3d images of the body in their minds whilst doing 2d scans. However, until recently it was almost impossibel to do this kind of reconstruction on on information using ultasound scanning. With the advent of baby scans for the first time allowed us a peek into the thinking of a sonologist and so 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 should be undertaken with an understanding of the risks involved.
