Abstract
Provided are an ultrasonic imaging method and device, and a storage medium. The ultrasonic imaging method includes: acquiring an ultrasonic echo signal; segmenting the ultrasonic echo signal into a first predetermined number of sub-echo signals according to scan depths; performing amplitude apodization on each sub-echo signal with a predetermined window function to obtain processed sub-echo signals; completing ultrasonic imaging according to the processed sub-echo signals. At least one sub-echo signal is subjected to the follow processing: segmenting the at least one sub-echo signal into a second predetermined number of unit echo signals according to the scan depths, and assigning a weighting coefficient to each unit echo signal; performing amplitude apodization on each unit echo signal with the corresponding predetermined window function, and weighting the unit echo signals with corresponding weighting coefficients to obtain processed unit echo signals; and forming a processed sub-echo signal from the processed unit echo signals.
