Baby scanning - baby ultrasound.co.uk
The method know as three dimensional ultrasound is used in early pregnancy, it can provide 3d pictures of the unborn child. Most of the time these ultrasound pictures are rapidly collected 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 pulses are sent from multiple directions. The ultrasound waves can be redirected back then captured to provide information to construct a 3 d picture in in the same way as 3d movies. 3 dimesional ultasound scanning was devised by olaf ramm abs stephen smith.
It’s important to understand that sonologists worldwide always pictured 3d pictures of the body in their minds while doing 2d scans. However, until recently it was almost impossibel to do this type of reconstruction on patient data acquired using ultasound scanning. The advent of 4d scans for the first time allowed us a view into the brain of a sonologist and hence letting us view the images on the ultrasound machine.
The 3d/4d ultrasound image 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 none medical situations should be undertaken with the understanding that a risk may exist.
