4d and 3d scans - baby ultrasound.co.uk
The method know as three dimensional ultrasound scanning is that can be used during early pregnancy, it can provide 3d pictures of the unborn child. Most of the time these ultrasound samples are quickly collected and joined together and animated to created a “4d ultrasound scan”.
Three dimensional scanning works in a similar manner to the usual ultrasound methods except that the ultrasound waves are directed from multiple directions. The ultrasound waves are redirected back then captured to provide information to construct a 3d image in very much the same way as 3d pictures. 3 dimesional ultrasound was devised in the usa.
It is important to understand that sonologists around the world have always conjured 3d images of the body in their minds whilst doing 2d scans. However, until recently it was difficult to do this type of reconstruction on on information using ultasound scanning. The advent of 4d baby scans for the first time allowed us a peek into the thinking of a sonologist and so allowing us see the images on the ultrasound machine.
3d 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 involved.
