Ultrasound imaging system and ultrasound imaging method

According to the ultrasonic imaging system and method, an ultrasonic probe emits ultrasonic waves to a target object and receives echo signals of the ultrasonic waves; the transmitting and receiving control circuit controls the ultrasonic probe to transmit ultrasonic waves and receive echo signals; the processor responds to selection of an inspection mode, ultrasonic imaging is conducted on the target object according to the first imaging parameters, a first ultrasonic image is obtained, and the inspection mode comprises a plurality of section types to be scanned; acquiring a first imaging mode of the first ultrasonic image; determining a first section type to which the first ultrasonic image belongs, wherein the first section type is one of a plurality of section types to be scanned; acquiring a corresponding second imaging parameter according to the first imaging mode and the first section type; performing ultrasonic imaging on the target object according to the second imaging parameter to obtain a second u
