A medical image created using sound waves, often used to see a baby during pregnancy or to examine internal organs.
From Latin 'sonus' (sound) + Greek '-gram' (a recording or picture). This modern word was created in the mid-1900s when ultrasound technology was invented.
Ultrasound was originally invented during World War II to detect submarines, but doctors realized it was perfect for seeing inside the body safely without radiation—so the same technology that found enemy ships now helps see babies before birth!
