What is a 3D Ultrasound, and What are its Benefits? Your Top Questions Answered

The traditional ultrasound – the 2D variety – has been in use for decades, and has served the medical community and a variety of patients very well. They are very popular and we all know someone who has benefitted from this technology. This technology is already outdated, however; there are newer and better versions employed, with a lot of advantages.


If you haven’t heard of the latest versions yet (3D and 4D ultrasound), then this one’s for you. What is a 3D ultrasound, and what are its benefits? Here are your top questions answered.

What’s 3D ultrasound?

We all know what 3D is; we’ve heard about it so often, especially when it comes to popular media such as motion pictures. In essence, 3D involves the imaging of three dimensions: height, width, and length. If you think of 2D as a sheet of paper, you can think of 3D as a box.

The 3D is developed by creating several 2D pictures, and software allows it to integrate the various 2D pictures (taken from different angles) into one 3-dimensional projection of the subject observed (in most cases the subject is a baby in the womb of the mother). When we speak of 4D, we add the element of time – hence, we have a series of 3D pictures that are placed in video mode.

The general advantages

There are many general advantages to 3D and 4D ultrasounds; here are just some of them:

  • More detail, which makes the experience of having a baby a more special one
  • More and quicker information regarding the baby’s features, and more
  • Better imagery, which allows the parent-to-be to see their baby in full detail – and even see them move

For the baby

It’s much better for the baby as well, of course; the specialist will be able to determine details and potentially detect issues such as cleft palate and cleft lip.

For the parents

The parents of the baby can have a much clearer view of their baby, and although 3D and 4D ultrasounds are only elective ultrasounds – and not medical ones which are usually prescribed by the doctor – it allows parents-to-be to actually see their baby and even observe how their baby moves, how it opens and closes its eyes, and see it smile and even suck its thumb. The experience provided by such an ultrasound is magical, to say the least.

Technology is constantly evolving, and when old-fashioned methods are improved upon – when 2D can grow into 3D and 4D elective ultrasounds such as the ones provided by – the benefits are exponentially increased. Thanks to these innovations, mothers- and fathers-to-be are sure to get much more information about their unborn child, see them in clearer detail, and be able to establish a greater and more special bond with them – and this is always a wonderful thing.
