PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic system and a method for generating IQ data without a quadrature demodulator. SOLUTION: The IQ data are generated by extracting at least a pair of data having a phase difference ofλ/4 from focused receiving signals output from a beam former at a rate of n-times of a center frequency of analog receiving signals.
