What is 4D ultrasound?

4D ultrasound adds time or motion to a 3D image. Hence the result is a moving 3D image. 2D images are the pictures produced for your diagnostic ultrasound and although they can be seen well by sonographers, they are often difficult to recognise to the untrained eye. 3D images are images taken in a 3D format; however they are usually at a higher resolution than 4D images.
