ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue‚ muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003)‚ muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue‚ muscle and bone In ultrasound‚ Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium
