1.	The wave velocity of ultrasound in soft tissues is 1540m/s and the impedance offered by it is 1.63 X 106 kg/m^2s. What is the density of the soft tissue?(a) 0.1058441 kg/m^3(b) 10.58441 kg/m^3(c) 1058.441kg/m^3(d) 105844.1 kg/m^3This question was posed to me in class test.My query is from Ultrasound in portion Diagnostic Investigation via Imaging Techniques of Clinical Science
Answer» Correct choice is (C) 1058.441kg/m^3 Explanation: The IMPEDANCE is GIVEN BYZ = ρc where Z = impedance, ρ = density and c = velocity of the ultrasound. Since the wave velocity and the impedance offered are given, ρ = z/c. This results in 1058.441 kg/m^3 of density for the soft tissue.
