Baby scans - babyultrasound.co.uk
The method know as three dimensional ultrasound scanning is used during early pregnancy, it provides 3d images of the fetus. Most of the time the ultrasound images are quickly collected and combined to produce a “4d ultrasound”.
Three dimensional scans works in a similar manner to the normal ultrasound methods except that the ultrasound pulses are directed from multiple directions. The ultrasound pulses are reflected back then captured to provide information to construct a 3-dimensional picture in very much the same way as 3d pictures. 3d ultrasound was started by stephen smith and olaf von ramm at duke university.
It’s important to understand that sonologists everywhere have always conjured 3d pictures of anatomy or pathology in their minds while doing their 2d scans. However, until recently it was difficult to do this kind of reconstruction on patient data acquired using ultasound scanning. The advent of 4d baby scans for the first time allowed us a peek into the brain of a sonologist and allowing us to reconstruct 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. There is no data to suggest harm due to 3d ultasound scanning, its use in none medical situations should be undertaken with an understanding of the risks that exist.
