Limited diffracting waves such X-wave have great potential applications in the enlargement of the field depth in acoustic imaging systems. In practice, the generation of real time X-wave ultrasonic fields is a complex technology which involves precise and specific voltage for the excitations for each distinct array element. In order to simplify hardware system of excitations pulse in X-wave, the complex excitations were instead by simple driving, which combination of rectangular and triangular driving pulses. The improved hardware system consists a computer for communication with the circuit, ...
