4d Baby Scans

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 ultrasound images are rapidly captured and joined together and animated to make a 4d ultrasound scan.
Three dimensional scans works in a similar manner to the normal ultrasound scanning methods except that the ultrasound pulses can be sent from multiple directions. The ultrasound waves are reflected back then captured to provide information to construct a 3-dimensional image in in a similar manner to 3d pictures. 3 dimesional ultasound scanning was devised by stephen smith and olaf von ramm.
It is important to understand that sonologists around the world always pictured 3d pictures of the body in their minds while doing 2d scans. However, until recently it was almost impossibel to do this kind of reconstruction on on information using ultrasound. With the introduction of 4d ultrasound for the first time allowed us a peek into the mechanics of thinking of a sonologist and hence letting 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 ultrasound, its use in non-medical situations should be undertaken with the understanding of the risks.
