Ideally, underwater ultrasound would use which type of water?

• A. Tap water
• B. Distilled water
• C. Seawater
• D. Saline water

Answer: (B)

Underwater ultrasound works best when the medium it travels through has minimal attenuation and scattering of the sound waves. Distilled water provides the lowest attenuation because it contains no dissolved minerals, salts, or particulates that can absorb or scatter the ultrasound energy. Tap water, seawater, and saline water all have dissolved substances that increase attenuation and can alter the wave's properties, reducing the energy reaching the target tissue. So distilled water is the ideal medium for underwater ultrasound.
