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...
