ultrasound
word
Definition
Ultrasound is a type of sound wave with a very high frequency, used in medicine to create images of the inside of the body (such as during pregnancy or to check organs).
Usage & Nuances
Most commonly used in medical settings: 'an ultrasound' means the imaging test itself, especially for pregnancy. Can also refer to the technology or the sound waves. The countable noun ('an ultrasound') usually means the scan/result, not the physical waves. Don't confuse with 'sonogram', which is the picture created from an ultrasound.
