Abstract
In this paper, an ultrasound flow imaging system with single-transmit coded excitation is studied. With the oversampled code sequence modulated by base code, code compression before or after demodulation is demonstrated to be equivalent. A coded excitation flow imaging system with relatively low analog-to-digital (AD) sampling rate is proposed. The performance of the system is evaluated by simulation results
