Ultrasonic scanner and ultrasonic signal correction method for the ultrasonic scanner

An ultrasound scanner includes;

• an ultrasound transducer that transmits ultrasound signals to a measurement object and receives ultrasound echo signals reflected from the measurement object;
• a single motor connected to a central axis of the ultrasound transducer;
• an ultrasound probe with the ultrasound transducer and motor mounted therein;
• a tilt sensor mounted on a central axis of the ultrasound probe to detect a tilt angle of the ultrasound probe with respect to a second direction;
• and
• a control unit acquiring sector-shaped 2D ultrasound images at a plurality of tilt angles in response to a change in tilt angle by manual manipulation, which the 2D ultrasound images are obtained by rotating the ultrasound transducer using the motor in a first direction perpendicular to the second direction,
• wherein the control unit receives the ultrasound echo signals from the ultrasound transducer, corrects the coordinates of the ultrasound echo signals by considering the tilt angle of the ultrasound probe by the manual manipulation, and acquires a sector-shaped 2D ultrasound image using the ultrasound echo signals with the corrected coordinates.
