摘要： An ultrasound diagnostic system and a method for forming IQ data without a quadrature demodulator are disclosed. Ultrasound echoes from a target object are converted into analog signals, which have a center frequency. The analog signals are converted into digital signals and parts of the digital signals are extracted at a rate of n-times of the center frequency, wherein "n" is a positive integer. Focused-receiving signals are formed with the extracted digital signals and IQ data are obtained by selecting at least one pair of the focused-receiving signals. The focused-receiving signals in each pair have a phase difference of »/4 with respect to each other, where " »" is a wavelength determined with the center frequency.
