Baby scans - babyultrasound.co.uk
The method know as 3d ultrasound scanning is used in early pregnancy, providing 3 d pictures of the fetus. Most times these ultrasound samples are rapidly captured and joined together and made into a movie to created a 4d scan.
Three dimensional scanning works in the same manner to the usual scanning methods except that the ultrasound scanning waves can be directed from multiple directions. The waves can be redirected back and captured and provide information to construct a 3-dimensional picture in in a similar manner to 3d pictures. 3d ultrasound was devised by olaf ramm and stephen smith.
It is important to understand that sonologists everywhere have always pictured 3d pictures of anatomy or pathology in their minds while doing 2d scans. However, until recently it was difficult to do this kind of reconstruction on patient data acquired using ultasound scanning. The advent of 4d baby scans for the first time allowed us a peek into the thinking 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. There is no data to suggest any harm due to 3d ultasound scanning, its use in none medical situations needs to be undertaken with an understanding of the risks.
