Ultrasonic imaging method and device

The invention discloses an ultrasonic imaging method and device, and the method comprises the steps: controlling an ultrasonic probe to emit ultrasonic waves for super-resolution contrast imaging to a target tissue containing a contrast agent, and receiving a returned ultrasonic echo signal for super-resolution contrast imaging; generating and displaying a super-resolution contrast image of the target tissue based on the ultrasonic echo signal for super-resolution contrast imaging; selecting one or more regions of interest from the super-resolution contrast image of the target tissue; and generating and displaying a pulse Doppler map of the one or more regions of interest based on the ultrasonic echo signals for super-resolution contrast imaging corresponding to the one or more regions of interest. According to the ultrasonic imaging method and device provided by the embodiment of the invention, various ultrasonic images are obtained by processing one ultrasonic echo signal, and the types and the number of th
