| description | The invention discloses an ultrasonic imaging method and device, electronic equipment and a storage medium. The method comprises the following steps: converting a received ultrasonic echo signal representing time change into a beam domain signal representing frequency change; performing compression processing on the beam domain signal by adopting a preset sampling matrix to obtain a virtual measurement signal; wherein the preset sampling matrix satisfies a limited equidistant property; the virtual measurement signal has sparsity; recovering the virtual measurement signal to a full array element state to obtain a virtual frequency domain signal; performing offset processing on the virtual frequency domain signal to obtain an actual frequency domain signal; and converting the actual frequency domain signal into a target image matrix for generating an ultrasonic image. According to the technical scheme provided by the invention, the image quality of ultrasonic imaging can be improved to a certain extent.
