What Is the Difference Between 3D & 4D Ultrasound Imaging?
3D ultrasound imaging creates a three-dimensional image of the fetus, providing a static, lifelike picture that shows detailed features and structures. This technique allows parents to see their baby's face, hands, and feet with more clarity than the traditional 2D ultrasound. On the other hand, 4D ultrasound imaging takes this a step further by adding the dimension of time, creating live video images of the fetus. This enables parents to observe real-time movements like kicking, stretching, or even facial expressions.
The main difference lies in the ability of 4D ultrasound to capture motion, which can be particularly reassuring and engaging for expectant parents. Both techniques use the same underlying ultrasound technology, but 4D ultrasounds require more advanced equipment and often a longer session to capture the video footage. While 3D ultrasounds are typically used for detailed anatomical assessments, 4D ultrasounds are more commonly chosen for keepsake videos and a deeper emotional connection.
