“4D” is shorthand for four-dimensional – the fourth dimension being time. As far as ultrasound is concerned, 4D is the latest ultrasound technology. 4D takes three-dimensional ultrasound images and adds the element of time to the process. This allows you to see your unborn baby in amazing real time detail.
