Example of an SDUV stiffness and viscosity measurement of an excised human prostate within one single region. (a) & (b): amplitude of displacement and phase of vibration records detected at 3 different locations, 1 mm apart. (c): shear wave speed vs. frequency. The stiffness and viscosity were μ1 = 1.80 kPa and μ2 = 1.09 Pa.s, respectively (d): Shear wave speeds calculated from 5 acquisitions to check the repeatability of (c). The mean stiffness and viscosity were μ1 = 1.78 kPa and μ2 = 1.11 Pa.s, respectively.
