Baby scanning - baby ultrasound.co.uk
The method know as 3d ultrasound is used during early pregnancy, it can provide 3d pictures of the unborn child. Most times these ultrasound samples are rapidly captured and joined together and animated to created a 4d ultrasound scan.
Three dimensional scans works in a similar manner to the usual ultrasound methods except that the ultrasound scanning pulses are directed from multiple directions. The waves are redirected back and captured and 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 everywhere always pictured 3d images of the body in their minds while doing 2d scans. However, until recently it was not possible to do this type of reconstruction on patient data acquired using ultrasound. The advent of ultrasound baby scans for the first time allowed us a view into the thinking of a sonologist and allowing us to reconstruct 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 harm due to 3d ultasound scanning, its use in non-medical situations needs to be undertaken with the understanding that a risk may exist.
