The invention relates inter alia to a method for examining human or animal tissue, wherein at least one time-harmonic mechanical excitation wave of predetermined excitation frequency is coupled into the tissue, the wave speed of a shear wave in the tissue caused by the mechanical excitation wave and having the frequency of the excitation wave is measured by means of an ultrasound method, and an elasticity measurement specifying the elastic properties of the tissue is determined using the measured wave speed.
