A method of obtaining a Doppler image of tissue, which is captured using an ultrasonic wave, the method including: transmitting an ultrasonic signal to a target object such that a plurality of ensembles are formed; receiving a ultrasonic response signal from the target object; filtering the received ultrasonic response signal by using a variable filter; estimating a frequency of the received ultrasonic response signal based on the filtered data; and generating the Doppler image of the tissue based on the estimated frequency. |
