摘要： A method for quantifying viscoelasticity of a medium includes: obtaining a position-time graph of vibration propagation after the medium is subjected to a vibration excitation, determining an angle with maximum signal energy in the position-time graph by using angle projection, where the angle with the maximum signal energy corresponds to a slope of the position-time graph and the slope of the position-time graph is the propagation velocity of the vibration in the medium. Since the propagation velocity of the vibration in the medium is related to the viscoelasticity of the medium, a viscoelasticity parameter of the medium can be quantitatively calculated after the slope of the position-time graph is obtained. The method does not need to select a feature point from the position-time graph to calculate the slope of the position-time graph, and can efficiently and accurately quantifies viscoelasticity of the medium.

摘要： An elasticity detecting probe comprises a probe body (1) and a control switch (3) for controlling on/off of the probe body (1), where the probe body (1) and the control switch (3) are separately arranged and the probe body (1) and the control switch (3) are coupled to each other electrically or wirelessly. The separate arrangement of the probe body (1) and the control switch (3), allows that an operator can operate the control switch (3) to turn on/off the probe body (1) by using other body parts rather than the two hands, thereby preventing the offset of the probe body (1) while turning on the control switch (3), and improving the detection accuracy.
