PURPOSE: A method and apparatus for obtaining the moving speed and direction of a tissue are provided to detect the moving speed and direction of the tissue in real time by using light which is not focused.CONSTITUTION: A data obtaining unit (110) obtains vector Doppler data from an object by transmitting and receiving an ultrasonic wave. A frequency converting unit (120) produces frequency spectrum information about the received vector Doppler data. A detecting unit (130) detects the moving speed and direction of a tissue based on the vector Doppler data. A display unit (140) displays the moving speed and direction of the tissue by overlaying the moving speed and direction of the tissue on an ultrasonic image of the object. A control unit (150) controls the data obtaining unit, the frequency converting unit, the detecting unit, and the display unit.COPYRIGHT KIPO 2013[Reference numerals] (110) Data obtaining unit (120) Frequency converting unit (130) Detecting unit (140) Display unit (150) Control unit초음파 신호를 송수신하여 대상체로부터 벡터 도플러 데이터를 획득하는 단계 및 획득된 벡터 도플러 데이터를 기초로 대상체에 포함된 조직의 이동 속도 및 방향을 검출하는 단계를 포함하는 것을 특징으로 하는 조직의 이동 속도 및 방향 획득 방법을 개시한다.
