Difference between 2D, 3D, and 4D Ultrasound

There are three different kinds of sonogram images. The choice of which type of image to use depends on the goals for a particular test. For elective sonograms most parents want to see their child in three dimension.
2D Ultrasound

The most common and type of ultrasound picture is a series of flat, two-dimensional cross section images of the scanned tissue. Referred to simply as 2d ultrasound, this mode of scanning is still standard for many diagnostic and obstetric situations after a half-century of use.
3D Ultrasound

In recent years, 2d ultrasounds have also been projected into three-dimensional representations. This is achieved by scanning tissue cross sections at many different angles and reconstructing the data received into a three-dimensional image. A common use for 3d ultrasound pictures is to provide a more complete and realistic image of a developing fetus.
4D Ultrasound

By updating 3d ultrasound images in rapid succession, sonographers can also create 4d ultrasound videos. In the 4d ultrasound, fourth dimension, time, adds movement and creates the most realistic representation of all.
