The invention relates to an ultrasonic image denoising method, electronic equipment and a storage medium, and the method comprises the steps: obtaining a plurality of continuous ultrasonic images; registering the adjacent ultrasonic images, and carrying out average value stacking to obtain a stacked image; performing downsampling processing on the stacked image, extracting a gradient image of the downsampled image, and calculating a gradient magnitude and a gradient direction of a pixel point according to the gradient image; taking the gradient amplitude and the gradient direction of the pixel point as matrix elements to generate a template mark matrix, determining the type of the pixel point, and setting the template mark matrix according to the type of the pixel point; selecting a non-tissue region part and a tissue region part in the downsampled image through the template marking matrix, performing Gaussian filtering on the non-tissue region part, and performing bilateral filtering on the tissue region par
