Shouting into flesh and listening to the echo to draw a picture.
means A medical imaging technique that uses high-frequency sound waves to create pictures of structures inside the body, like organs, tissues, or a developing fetus.
from Built from Latin 'sonus' (sound) plus Greek-derived '-graphy' (writing or recording) — the same suffix family that gives us photography and geography. The word itself is a 20th-century coinage, assembled once the sound-wave technology existed to need naming — so unlike older words, its origin is less a story and more straightforward engineering: sound, written down.
