3D and 4D Ultrasound Background
An ultrasound is the interpretation of reflected sound waves to form a picture of the baby. 2D ultrasound (sometimes referred to as “traditional” ultrasound) has been safely used in obstetrics for over 35 years.
2D ultrasound works by “listening” to sound waves in a single plain. The ultrasound is directed straight down and reflected back up again. Think of it as being able to virtually slice a loaf of bread. The resulting black and white image is similar to looking at the face of a slice of bread.
3D ultrasounds work by a different process known as “surface rendering”. In this case, the same sound waves used in 2D are sent down – this time at different angles. These reflections are interpreted through sophisticated software, and a 3D image of the baby is instantly created. Using the same “bread” analogy as before, the surface of the loaf is now being examined from the outside. Surface details can now be visualized with remarkable clarity.
4D ultrasound is captured in the same manner as 3D ultrasound. Instead of looking at a single still image (3D), you are now able to view live “video” of the baby in the womb (4D).
The Positive Impacts of Bonding using 3D Ultrasound and 4D Ultrasound
Expectant mothers nationwide are seeking elective ultrasounds because they feel it will have a positive impact during their pregnancy. Recent studies have shown that viewing an ultrasound can cause marked improvement in maternal health habits. Studies presented at an American Institute of Ultrasound in Medicine (AIUM) meeting have even supported that 3D ultrasounds will positively influence parents bond with their babies.
Mothers tend to improve their diets, exercise more, and eliminate harmful behaviors such as smoking or drinking. Other ultrasound benefits may also include increased paternal involvement, family support, empathy, and appreciation.
