1. A vibration generating system for elastography equipment, comprising:
a control computer comprising a control signal generator and a waveform generator:
a pressure source comprising a compressed air source;
a pressure regulating communicator;
and a vibration transducer:
wherein the pressure regulating communicator is in fluidic communication with the pressure source and vibration transducer, respectively;
wherein the vibration transducer is used to transmit vibration according to a pressure acting thereon;
wherein the control computer is coupled to the pressure regulating communicator, characterized in that the control computer is configured to obtain control parameters by using a look-up table module according to inputted elastography conditions, so as to control the pressure regulating communicator;
wherein the pressure regulating communicator comprises a pressure excitation valve and a pressure setting mechanism arranged upstream of the pressure excitation valve, the pressure setting mechanism comprising a pressure setting valve, the pressure setting valve being arranged downstream of the pressure source and in fluidic communication with the pressure source;
wherein the control signal generator is coupled to the look-up table module and the pressure setting mechanism, and is configured to generate a target input for the pressure setting mechanism on the basis of at least one of the control parameters obtained using the look-up table module, so as to control the pressure setting mechanism;
wherein the look-up table module stores correlations between various elastography conditions and control parameters for the pressure regulating communicator; and
wherein the waveform generator is coupled with the look-up table module and the pressure excitation valve, and is configured to, based on the at least one of the control parameters obtained by the look-up table module, generate a waveform signal as a control signal for controlling the pressure excitation valve.
