Ultrasonic diagnostic imaging system and control method thereof

An ultrasonic diagnostic imaging system provided with an ultrasonic probe and an image processing section that converts a signal generated when the ultrasonic probe receives ultrasound reflected from an examinee to image information, comprising:

• a measuring unit that measures a relative position and a relative posture of the ultrasonic probe with respect to the examinee using image information on the examinee acquired by the ultrasonic probe;
• a control amount calculation unit that calculates an amount of control of the position and posture of the ultrasonic probe based on the measurement result of the measuring unit;
• and
• at least one of a probe control mechanism that controls a position and posture of the ultrasonic probe using the amount of control calculated by the control amount calculation unit and a guiding information presentation unit that presents information for guiding movement of the position and posture of the ultrasonic probe using the amount of control calculated by the control amount calculation unit.
