Phased array is an advanced pulse-echo technique utilizing multiple miniaturized transducers and time-delays to shape the ultrasonic sound beam in a desired angle and focus. Therefore the technique has a wide range of applications

A phased array probe houses an array of ultrasonic transducers which are acoustically insulated from each other. By pulsing the elements with different time-delays, the angle of the ultrasonic sound is ‘steered’ to a specific angle, focus-point or both
