3D / 4D ultrasound is an ultrasound technique used during pregnancy, to produce lifelike images of the fetus. We offer this to those who are interested for entertainment purposes from 26 weeks of pregnancy.and onwards.

The standard obstetric diagnostic scans are 2-dimensional (2D) scans. All women are advised to have a scan at 12 and 20 weeks of pregnancy (see pregnancy brochure). An ultrasound-trained Obstetrician performs these scans at WUMe.

In 3D/4D fetal ultrasound scanning, the sound waves reflected from the fetus are processed by a sophisticated computer program which results in recognisable surface-rendered images of the fetus. 4D scanning is 3D scanning in real-time, like a movie. A registered sonographer will perform this scan.

We use ultrasound at energy levels below the Australasian Society for Ultrasound in Medicine limits for obstetrical ultrasound. These standards apply to both 2D and 3D/4D ultrasound examinations in this practice. While there is no hard evidence for harmful effects of 3D/4D ultrasound, its use in non-medical situations should be undertaken with the understanding that some effect may exist. In view of this, the scan time for your 3D/4D scan will be kept to a minimum and be no more than 15 minutes.

The criteria to be eligible for a 3D /4D scan in our practice are that you :

  • Are currently receiving obstetric care from an Obstetrician or hospital antenatal clinic.
  • Have previously obtained a diagnostic ultrasound between 18 and 22 weeks
  • Acknowledge that no medical advice or assistance in relation to your pregnancy will be provided.
  • That you sign a disclaimer.


Every attempt will be made to achieve high quality images but there may be times when it is not possible to achieve good views of the face.

Hope you enjoy the 3D ultrasound experience of your fetus.
