Abstract: A control system for an ultrasound transmission/reception apparatus with a plurality of acoustic transducers for transmitting and receiving ultrasound signals may include driving device operatively coupled to the acoustic transducers and a control unit. The control unit may cyclically control the acoustic transducers in a transmission state for transmitting ultrasound signals, and in a reception state for receiving echoes of the transmitted ultrasound signals. The control unit may include an input stage which receives an external timing signal, and a processing stage which detects a first edge of the timing signal to determine the start time of a transmission phase during which the acoustic transducers are controlled in the transmission state, and a second edge of the timing signal to determine the stop time of a reception phase during which the acoustic transducers are controlled in the reception state.
