    • A method for forming an ultrasound image by decreasing decorrelation of elastic signal is provided to reduce errors in the conversion of a phase value into a time value by computing an instantaneous frequency changed according to a depth of a subject. A first reception signal and a second reception signal are received from an ultrasound signal reflected from a subject, in which a delay time between the first receive signal and the second receive signal is varied according to a depth of the subject. A first delay time between the first reception signal and the second reception signal is estimated. One of the first and second reception signals is shifted as the estimated delay time. After the shift is completed, a second delay time between the shifted signal and the non-shifted signal is computed. A third delay time between the first and second reception signals is computed based on the estimated first and second delay times. An ultrasound image is formed based on the third delay time.

A transceiver(110) forms a Doppler signal by transmitting and receiving an ultrasonic signal for forming a Doppler mode image as a pulse repetition frequency. A signal processing unit(120) produces a first mean frequency of the Doppler signal based on the n-th Doppler signal and the (n-1)-th Doppler signal. The signal processing unit produces the second mean frequency of the Doppler signal based on the n-th Doppler signal and the (n-k)-th Doppler signal. The signal processing unit performs the first signal processing for reducing the influence of the noise and the second signal processing for compensating for the aliasing of the Doppler signal based on the first mean frequency and the second mean frequency when estimating the Doppler frequency. An image processing unit(130) forms the Doppler mode image based on a Doppler signal outputted from the signal processing unit.
