Ultrasonic acoustic absorption measurement method, ultrasonic acoustic absorption measurement system, and computer-readable non-convertible storage medium for measuring ultrasonic acoustic attenuation

摘要

Acoustic absorption or attenuation of ultrasound is measured. To estimate acoustic absorption or attenuation, the displacement of tissue caused by stress at different frequencies is measured. The absorption or attenuation is calculated from the displacements. The incorporation of different frequencies provides another variable for solving for attenuation or absorption despite unknown tissue stiffness.
