What term describes the resistance of tissue to sound?

• A. Sound speed
• B. Acoustic impedance
• C. Reflection
• D. Refraction

Answer: (B)

The term that describes the resistance of tissue to sound is acoustic impedance. It quantifies how much sound pressure is required to produce a certain sound wave in a given medium and is influenced by both the density of the tissue and the speed of sound within that tissue. Acoustic impedance is crucial in medical ultrasound imaging, as it helps to determine how much of an ultrasound wave is transmitted into the tissue versus how much is reflected back. In ultrasound, different tissues have different acoustic impedances, which affects the amount of reflection and transmission that occurs at tissue interfaces. When sound travels from one medium to another with different acoustic impedances, part of the sound is reflected at the boundary, which can be detected and used to create images in diagnostic imaging. Understanding acoustic impedance is essential for interpreting ultrasound results and assessing tissue properties.
