We are proud to be one of only a few clinics in Kentucky that currently offer 4 dimensional ultrasounds by GE.,"4D" is shorthand for "four-dimensional"- the fourth dimension being time. As far as ultrasound is concerned, 4D Ultrasound is the latest ultrasound technology and it is exclusive to GE. 4D Ultrasound takes three-dimensional ultrasound images and adds the element of time to the process. The result: Live Action images of your unborn child or of any internal anatomy.
