A 3D ultrasound uses sound waves just as a 2D ultrasound does, but instead of transmitting the waves straight though the tissue and organs and back again, it emits the wave at various angles. This results in a three-dimensional image. A 2D ultrasound provides a flat image, whereas a 3D ultrasound shows depth, contour and detail.
A 3D ultrasound is the groundwork for a 4D ultrasound. 4D allows one to view movement using a compilation of 3D images. Movements like the motion of the heart and even a yawn can be seen in real time.
A diagnostic ultrasound is provided to you by your primary health care provider (OB, GP, or midwife). This is generally done between the 18th and 20th weeks of pregnancy. This type of ultrasound is used to detect any abnormalities in the fetus or mother and is usually preformed in 2D and by a registered sonographer. The results of this ultrasound will be discussed with you by your primary health care provider.
3D/4D keepsake imaging is non-diagnostic and is only used as a keepsake image. It captures images of the baby during the pregnancy in 3D. It should never replace the the routine ultrasound that is provided to you by your health care provider.
