Ultrasonic impact pattern recognition apparatus and method

The present invention authenticates the user by using the impact pattern, the present invention relates to ultrasonic apparatus and method for converting an ultrasonic diagnostic mode. Ultrasonic jangchieun of the present invention, by using the ultrasonic reflection signal reflected from the target object ultrasound diagnostic unit operable to form an ultrasound image; A user impact detecting unit configured to form an impact pattern information by detecting an impact applied to the ultrasound diagnostic unit; A storage unit for storing a mapping table that provides the execution instruction for the diagnostic mode corresponding to the user password, the impact pattern information, and each of the plurality of impact pattern information corresponding to the user's password; And includes the impact pattern information, the user password, the impact pattern information and control unit for using the mapping table, controls the driving of the authentication and the ultrasonic diagnosis of said user, and operative to control said ultrasound diagnostic unit diagnostic mode execution . Ultrasonic, impact pattern, decryption, to change the diagnostic mode
