Baby Scans
The method know as 3d ultrasound is that can be used during early pregnancy, it provides 3d images of the unborn child. Most of the time these images are rapidly collected and combined and animated to make a 4d scan.
Three dimensional scanning works in a similar manner to the normal ultrasound scanning methods except that the ultrasound scanning pulses can be directed from multiple directions. The ultrasound waves can be redirected back and captured and provide information to construct a 3d image in very much the same way as 3d pictures. 3d ultrasound was devised in the usa.
It’s important to understand that sonologists worldwide have always pictured 3d pictures of the body in their minds whilst doing 2d scans. However, until recently it was almost impossibel to do this kind of reconstruction on on patient information using ultrasound. With the introduction of 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.
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 non-medical situations should be undertaken with the understanding that a risk may exist.
