What is 3D Ultrasound?
Traditional ultrasonography is performed with two-dimensional (2D) images of anatomy taken from multiple angles. This is done because ultrasound waves travel in a straight plane and cross through the structure in question in the same way that a knife cutting through fruit would. Naturally, since bodily structures and organs are three-dimensional (3D) objects we aim to acquire as many different imaging planes as possible in order to assess as much of the physical structure as possible. In an effort to expand our ability to see from all angles, ultrasounds can be performed using 3D imaging technology. 3D pictures give the healthcare team the ability to see structures (such as a fetus or a heart) as a model that can be rotated, sliced and assessed from all sides.
