1. A contrast enhanced imaging method, comprising:
receiving a first instruction;
determining a first imaging mode from preset imaging modes in response to the first instruction, wherein the first imaging mode comprises a first frame rate, and the first frame rate is pre-configured with first imaging parameters comprising a first line density and a first number of times for transmitting ultrasound waves;
transmitting first ultrasound waves in the first number of times to a target object and receiving first ultrasound echoes returned from the target object according to the first imaging mode to obtain first ultrasound echo signals;
generating a first contrast enhanced image having the first frame rate in the first line density according to the first ultrasound echo signals;
receiving a second instruction;
determining a second imaging mode from the preset imaging modes in response to the second instruction, wherein the second imaging mode comprises a second frame rate greater than the first frame rate, and the second frame rate is pre-configured with second imaging parameters comprising a second line density less than the first line density and a second number of times for transmitting ultrasound waves, wherein the second number of times for transmitting ultrasound waves is less than the first number of times for transmitting ultrasound waves;
transmitting second ultrasound waves in the second number of times to the target object and receiving second ultrasound echoes returned from the target object according to the second imaging mode to obtain second ultrasound echo signals; and
generating a second contrast enhanced image having the second frame rate in the second line density according to the second ultrasound echo signals.
