Abstract:The purpose of this paper is to explore the method for measuring Young’s modulus of soft tissues using ultrasonic
compression wave. The propagation speed of ultrasonic compression wave in isolated pig muscle tissues and pig liver tissues were
measured using the ultrasonic echo principle, and compared with the accepted values. The results showed that our results were close
to the accepted values, which could meet the research needs. Then, the relationship between the propagation speed of the ultrasonic
compression wave in soft tissues and the Young’s modulus of soft tissues was derived using the relevant formulas. This method
for measuring Young’s modulus has small requirements on the shape of the test tissues and less damage to the test tissues, and can
complete the measurement of the Young’s modulus of the biological tissues in vivo. This method is simple and easy to implement.
