What are benefits of a 4-D scan during the 2nd or 3rd trimester of pregnancy?

4-D ultrasound uses the same technology as 3-D ultrasound, but the images are recorded and played back in succession. This creates a moving image of the fetus in 3-D. Parents can watch as their baby moves and kicks in the womb. While 4-D ultrasounds can be used for diagnostic purposes, in many cases the images created are used for personal satisfaction and bonding between parents and the fetus.
