Etymology

Origin of sonogram

First recorded in 1955–60; sono- + -gram 1

Explanation

In medicine, a sonogram uses sound waves to display an image of some internal part of a person's body. A pregnant woman might have a sonogram to get a picture of her fetus. A sonogram most commonly produces a two-dimensional black and white image — for example, of a fetus inside its mother's uterus. Doctors use sonograms to see organs, tendons, muscles, and joints as well. A sonogram works by bouncing high frequency sounds against tissue and displaying the reflected or echoed image. The word itself combines the Latin sonus, or "sound," and the word-forming suffix -gram.
