4d baby scans - www.babyultrasound.co.uk
The method know as 3d ultrasound is used when a woman is in early pregnancy, it can provide 3d pictures of the unborn child. Most times these pictures are captured and combined to produce a 4d ultrasound scan.
Three dimensional scanning works in a similar way to the normal ultrasound scanning methods except that the ultrasound pulses are sent from many directions. The ultrasound pulses can be reflected back and captured and provide information to construct a 3 d picture in very much the same way as 3d movies. 3 dimesional ultasound scanning was started by stephen smith and olaf von ramm at duke university.
It’s important to understand that sonologists around the world have always conjured three-dimensional images of anatomy or pathology in their minds while doing their 2d scans. However, until recently it was impossible to do this type of reconstruction on on patient information using ultrasound. With the introduction of baby scans for the first time allowed us a peek into the brain of a sonologist and hence letting us view 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 ultrasound, its use in none medical situations needs to be undertaken with an understanding of the risks that exist.
