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

Vibration generating system for elastography equipment and control method thereof

The invention relates inter alia to an elastography device having at least one excitation unit () for generating mechanical tissue movements in human or animal tissue, and an image-recording device. It is provided according to the invention that the excitation unit () has: at least one pressure source (), at least one pressure-dependently operating actuator () for generating mechanical movements, at least one controllable valve () which is arranged between pressure source () and actuator () in terms of gas flow and the valve position of which influences the pressure acting on the actuator (), and a control device () which is connected to a control port of the valve () and which actuates the valve () and defines the valve position thereof and, in order to generate the mechanical tissue movements, varies the valve position, and thus the pressure acting on the actuator (), over the course of time.
