3D & 4D Imaging in Sydney – a baby’s image to keep for life

3D imaging is where you can see a more lifelike image than the traditional 2-dimensional scan.

4D imaging (Sydney) is where 3 dimensional images are taken repeatedly so that, over time, you can see the movements of the foetus.  So, you can see live movements of your baby in-utero, like a video.

How do we take 3D and 4D ultrasounds?

We use the same ultrasound beams as the conventional 2D scans.  The difference is the increased processing performed by the computer in the ultrasound machine, to highlight your baby’s features.  This is just as safe as 2D scanning, with no harm to your baby.

Overall, the use of 3D and 4D imaging is purely for the sake of the parents, so you can get a better image of your baby and enjoy the bonding experience.  There are only a few limited conditions where this is used for diagnostic purposes.

When is the best time to get these done?

When your baby is between 24 and 34 weeks is the best time to obtain good images.

We first undertake routine 2D scans to check that your baby is healthy and growing at the expected rate.  After we have all the routine measurements done to our satisfaction, then we can do 3D images, if you request these.

Please note: The best method for diagnostic ultrasound imaging of the foetus is still 2D ultrasound. The majority of our scans will be in 2D. Note 3D ultrasound has diagnostic role in structural issues eg cleft lip/palate, club foot, spina bifida etc.

Our sonographers are well trained in 3D/4D ultrasound and will always try whenever possible to take a 3D image of baby at the end of the exam.

It is important to note that our ultrasound service doesn’t encourage appointments for “entertainment only” 3D scans i.e. which are not medically indicated.
