The console is configured to execute instructions for dynamically adjusting a distance of activated ultrasonic transducers from a predefined target or area, an orientation of the activated ultrasonic transducers to the predefined target or area, or both the distance and the orientation of the activated ultrasonic transducers with respect to the predefined target or area. The display screen is configured to display a graphical user interface including the ultrasound images processed by the console from the corresponding electrical signals of the ultrasound signals.
