摘要： A vibration generating system (100) for elastography equipment and a control method thereof, elastography equipment, a method for controlling the vibration generating system (100) for elastography equipment, a method for operating the elastography equipment, and a corresponding computer-readable medium. The vibration generating system (100) for elastography equipment comprises: a control unit (1), a pressure source (2), a pressure regulating unit (3), and a vibration transmitting unit (4). The pressure regulating unit (3) is in fluidic communication with the pressure source (2) and the vibration transmitting unit (4), respectively. The vibration transmitting unit (4) is used to transmit vibration according to a pressure acting thereon. The control unit (1) is coupled with the pressure regulating unit (3). The control unit (1) is configured to obtain a control parameter by using a look-up table module (12) according to inputted elastography conditions, so as to control the pressure regulating unit (3).
