Baby scans - babyultrasound.co.uk
The method know as 3d ultrasound scanning is used when a woman is in early pregnancy, providing 3 d pictures of the fetus. Most times the ultrasound pictures are rapidly captured and combined and animated to produce a 4d ultrasound scan.
Three dimensional scanning works in a similar way to the normal ultrasound methods except that the ultrasound pulses can be directed from multiple directions. The waves are reflected back and captured and provide information to construct a 3d image in in the same way as 3d movies. 3d ultrasound was devised in the usa.
It’s important to understand that sonologists around the world always pictured 3d images of the body in their minds whilst doing 2d scans. However, until recently it was very difficult to do this type of reconstruction on on patient information using ultrasound. The advent of 4d baby scans for the first time allowed us a peek into the mechanics of thinking of a sonologist and so allowing us see 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 ultasound scanning, its use in none medical situations should be undertaken with the understanding that a risk may exist.
