The advantage of 4D ultrasound is that in showing the developing baby in three dimensions and in motion, it is much easier to see the baby clearly. Ultrasound scans are very important for many parents, since they not only serve to monitor the development of the baby, but also to show the first images of the foetus, which can be retained as a memory or souvenir. What is the aim of 4D ultrasound scanning? When this 3D image is refreshed in real time, it results in a live video known as a 4D ultrasound. Traditional ultrasound scans produce a flat 2D image, but modern technology can combine data from scans taken by the probe from different angles to create a 3D image. How do 4D ultrasound scans differ from more traditional scanning? The doctor administers a small amount of cold gel on the belly of the pregnant woman, and uses a probe to capture the images of the uterus and project them on a screen. These sound waves are emitted by a probe or transducer, which is passed over the region to be scanned by the doctor.ĭuring pregnancy, this test is performed to observe the status and development of the foetus without exposing it to radiation. As well as providing a high-quality image of the foetus, 4D ultrasound can be used for diagnostic imaging, allowing a healthcare specialist to observe the body's structures and tissues.ĭuring pregnancy, 3D ultrasound allows you to see three-dimensional images of your baby in the womb (as opposed to the traditional 2D images), while with 4D technology the image is constantly updated in real time and you can see it moving in the form of a video.ĤD ultrasound, like other ultrasound scans, uses high-frequency sound waves to generate images of organs and tissues inside the body.

Ultrasound is an imaging technique which allows a foetus to be observed in real time in the womb. Edited by: Conor Lynch What is 4D ultrasound?
