A hydrophone measures which property?

A hydrophone measures which property?

• A. Acoustic pressure output
• B. Doppler accuracy
• C. Penetration
• D. Contrast resolution

Answer: (A)

Hydrophones are designed to detect the pressure fluctuations of a sound wave in a fluid. They convert those acoustic pressure variations into an electrical signal, giving you the acoustic pressure output of the ultrasound beam. This makes them ideal for characterizing beam strength and verifying transducer output. Doppler accuracy, penetration, and contrast resolution relate to velocity measurement, tissue penetration depth, and imaging quality in tissue, respectively, and are not what a hydrophone measures.
