Diagnostic Imaging

4D Ultrasound

Taking a traditional three dimensional image and adding the fourth dimension of time, this new technology allows an expectant mother to see her baby's movement in the womb. During the test, the sound waves from the ultrasound are interpreted by the transducer and ultrasound machine to display 2D images and 3D/4D volumes. 4D ultrasounds are used by physicians and sonographers to help monitor the progress and development of a baby in the womb.

Frequently Asked Questions

How does an ultrasound work?

For an abdominal scan, ultrasound gel is applied to the belly. An ultrasound transducer is then used to send sound waves into the body.

What is being looked for?

In the first trimester, a vaginal ultrasound is often performed and is used to verify heart beat, look for multiples, and to set due dates. In addition, an ultrasound in the first trimester can rule out abnormalities such as ectopic pregnancy or potential for miscarriage. In the second trimester, abdominal ultrasound is performed. A full anatomical survey is performed and measurements are taken to verify growth and detect fetal development problems. In the third trimester, ultrasound is used to analyze fetal growth and movement and to ensure fetal and maternal well-being. Your physician will determine the need for and timing of your ultrasound scan(s).
