A delayed-excitation ultrasonic imaging method, device and delayed-excitation system. The method comprises: generating a regulation clock, and performing, according to the regulation clock, delayed excitation on an ultrasonic transducer once or multiple times (S102); performing data acquisition of ultrasonic echo signals of the ultrasonic transducer and signals generated after each instance of delayed excitation (S104); performing synthesis and superimposition of the acquired data to obtain high-frequency sampling data (S106); and performing ultrasonic imaging according to the high-frequency sampling data (S108). A delayed-excitation ultrasonic imaging device and system are also provided, and can realize high-frequency ultrasonic imaging via low-frequency sampling and delayed excitation by performing delayed excitation on the ultrasonic transducer, thus significantly reducing costs. La présente invention décrit un procédé d'imagerie ultrasonore à excitation retardée, un dispositif et un système à excitation r
