    • PURPOSE: An ultra-sonograph capable of using the vector Doppler and an ultrasonoic image producing method are provided to provide the reliable color Doppler image or the Doppler spectrum image to an inspector. CONSTITUTION: An ultrasonic signal is transmitted to a fixed point which is included in an object (S110). At least three answer signals reflected from the fixed point are received (S120). At least two answer signals among the received at least three answer signals are selected (S130). The vector information, which shows the speed and moving direction of the fixed point based on the receiving angle of at least two answer signals and the Doppler frequency, is obtained (S140). [Reference numerals] (AA) Start; (BB) End; (S110) Transmit an ultrasonic signal to a fixed point; (S120) Select at least three first answer signals reflected from a fixed point; (S130) Select at least two among at least three first answer signals; (S140) Obtain the vector information of the fixed point based on the receiving angle of at least two answer signals and the Doppler frequency
