Study on adopting optimum binary phase serial to enhance SNR and Penetrating of Ultrasonic Images

This paper present adopting optimum binary phase serial to enhance signal to noise ratio and Penetrating of Ultrasonic Images. It combine the advanced theory of radar, spread spectrum communication theory and technique of pulse reflection ultrasound imaging. It completely expatiates the feasibility of coded pulse compression technique applied to medical ultrasound system. Since the signal to clutter ratio (SCR) couldn´t meet the requirement of medical ultrasound imaging when adopting self-correlation decoding for optimum binary phase serial, this paper presents the CSIFIR(codes spectrum inverse filter) decoding filter and practical and efficient solutions based on the least mean square. The results show the validity of theories and the efficiency of the methods.
