What’s in a dimension?

We use 2D or 2 dimensional ultrasound imaging for all medical ultrasound scans. This is used not only to look at pregnancies and assess the wellbeing and growth of a baby, but at Sound Radiology we also use it to look at organs (such as kidneys, liver), blood vessels throughout the body, muscle and tendon problems, breast imaging and use it to guide biopsies and treat some problems with injections. 2D imaging is the black and white single view image that you see. The 3D or 3 dimensional image is where the specialised ultrasound probe is able to collect consecutive data and reconstruct it into a surface view or 3D view across an area, such as your baby’s face. 4D or 4 dimensional is the 3D view in real time allowing us to watch the expressions on your baby’s face, yawning and watch how your baby moves. The 3D and 4D ultrasound baby images are best seen later in the pregnancy when your baby’s features are prominent. See our blog on the best times for 3D and 4D scans.
