1. A method for forming a contrast pulse sequence ultrasound image, comprising:
generating at least three mutually different pulses having a same amplitude and a same frequency with differences in both pulse width and phasing, wherein generating the at least three mutually different pulses comprises: generating a first pulse having a pulse width corresponding to one half of a predetermined pulse width, generating a second pulse having the predetermined pulse width and having a delayed phase difference of 180 degrees with respect to the first pulse, and generating a third pulse having a same pulse width as the first pulse and having a delayed phase difference of 90 degrees with respect to the first pulse;
sequentially transmitting at least three transmission signals corresponding to the at least three mutually different pulses to an ultrasound transducer;
transmitting, by the ultrasound transducer, at least three ultrasound signals to a target object by sequentially generating the at least three ultrasound signals based on the at least three transmission signals;
generating, by the ultrasound transducer, at least three reception signals by sequentially receiving at least three echo signals reflected from the target object; and
forming the contrast pulse sequence ultrasound image by eliminating a linear component from the at least three reception signals.
