The most modern ultrasound technology is now available at Ascot Radiology; 4D ultrasound and live 3D with the market-leading GE Voluson, and more recently, the GE E8, being installed for the first time in New Zealand.

What is 4D Ultrasound?

4D is the fourth dimension in ultrasound when a 3D image has another dimension; time! 4D is the latest ultrasound technology. It takes many conventional 2D images, creates a surface rendered 3D image, and adds time to the process. The result is realistic live action images of your unborn child. 4D Ultrasound represents the difference between video and a still photograph. Through this revolutionary technology, your baby's 3D image is continually updated providing a live action view. It is a very fast process using a large volume of data to reconstruct the images over and over giving a moving image.

What are the advantages?

4D ultrasound is frequently used to look at the surface of the face or other fetal structures which, when surrounded by amniotic fluid, are given a lifelike image. It often makes images easier to understand for those not used to looking at conventional 2D images. It can give amazing lifelike pictures to expectant parents. It is used to enhance visualization of fetal abnormalities, picked up by conventional imaging, such as cleft lip, so that parents can recognize what the doctors are describing.

Are there any risks related to 3D/4D ultrasound?

No. 3D and 4D ultrasound both utilize sound waves only to look inside the baby, in the same way as ordinary 2D ultrasound.

Can we always get a good image of baby's face?

Often a good image can be obtained, but not always. As with conventional 2D imaging, baby's position, maternal size and the amount of amniotic fluid play a vital role in the quality of the picture. To get an ideal surface rendered image, the surface must only have fluid around it. If an arm is over the face or the face is up against the wall of the uterus, a good image may not be possible. 26 to 32 weeks is the ideal time for scanning as there is more amniotic fluid and the baby has developed some soft tissue about the face. However, 4D imaging can be attempted at any stage beyond 12 weeks.
