System and method for impact pattern recognition ultrasound

PURPOSE: An impact pattern recognition ultrasonic system and a method thereof are provided to change a diagnosis mode as simply performing user authentication by inputting an impact pattern, without carrying out a complex procedure. CONSTITUTION: An ultrasonic diagnosing unit(120) forms an ultrasonic image through an ultrasonic reflection signal. An impact sensing unit(130) senses impact applied to the ultrasonic diagnosing unit from a user. A controller(160) controls driving actions of the ultrasonic diagnosing unit and authentication of the user through impact pattern information, user password impact pattern information, and a mapping table. The controller compares the impact pattern information with the user password impact pattern information.
