Quick facts on 3D and 4D ultrasound scans you should know about


Mothers and fathers who are expecting a child are naturally excited to undergo a first ultrasound scan, with the hope and expectation they will be able to see a glimpse of their unborn little one. Unfortunately, the traditional 2D scan often results in a screen projection or print-out of an unclear black and white or grey blur where you have to squint your eyes to make out any discernible image – too much disappointment.

Fortunately, technology has come a long way, and much clearer images can be made thanks to improved versions: 3D and 4D technology. If you haven’t heard about it, then this one’s for you: here are some quick facts on elective 3D and 4D ultrasound scans you should know about.

The extra dimensions

We all know about 2D – that’s height and width, similar to a normal photograph. For 3D, we add another dimension (depth), so the image becomes one that can be rotated, to be viewed from different angles. It’s formed by taking several 2D images and having software integrate these into one 3D-model. When we talk about 4D, we’re talking about several 3D images over time (time is the 4th dimension). Hence, it’s 3D in movie format.

More information

The 3D and 4D imagery allows for much more detailed and specific images of the baby – and it’s usually done in under 45 minutes.

Better images for a better bond

This ability to get more detailed information about the baby is great. With a 3D or 4D ultrasound, the parent-to-be is able to see more detail and a clearer image of her unborn child, and this allows for a much better bond between the would-be mother and her baby. The experience of seeing your little one in 3D or 4D ultrasounds cannot be missed – and even though these types of ultrasounds are elective, it is still chosen by a lot more parents-to-be today just because they want to have a more enhanced bond with their baby.


The scans are just as safe as 2D scans, because the 3D and 4D images are actually created by having several 2D scans taken, which are then (through software) integrated into a 3D or 4D image.

The best images

The best images are taken when the mother is between 26 and 30 weeks pregnant; by that time the baby already has some fat and the image of bones will be less. After 30 weeks the head may already have shifted to the pelvis, so the face may not be seen.

The advantages of technology keep on accumulating, and this benefits both the medical community and the patients, as well as numerous people directly affected by these marvels. Remember, however, that ultrasound scans should still be done with safety in mind, as affirmed by 3D and 4D ultrasound specialists from Insideviewultrasound.com. Enjoy the new technology, but choose the right specialists to give you the service.
