Method, system, and storage medium for ultrasonic imaging

A method for ultrasound imaging, comprising:

• determining a first relative position corresponding to each emission of a plurality of ultrasonic waves based on emission times and/or an emission order of the plurality of ultrasonic waves, to obtain a plurality of first relative positions corresponding to a plurality of emissions of the plurality of ultrasonic waves;
• mapping the plurality of first relative positions distributed at equal intervals to a plurality of second relative positions distributed at unequal intervals corresponding to the plurality of emissions;
• determining an emission distance and a focus radius corresponding to the each emission based on an emission parameter and a second relative position corresponding to the each emission;
• determining a focus position corresponding to the each emission based on the emission distance and the focus radius corresponding to the each emission;
