Title:
ULTRASONIC IMAGING METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/180161
Kind Code:
A1
Abstract:
An ultrasonic imaging method and device, and a storage medium, the ultrasonic imaging method comprises: acquiring an ultrasonic echo signal (S102); dividing the ultrasonic echo signal into a first predetermined number of sub-echo signals according to a scanning depth (S104); using a predetermined window function to perform amplitude apodization on each sub-echo signal, so as to obtain processed sub-echo signals (S106); according to the processed sub-echo signals, completing ultrasonic imaging (S108); executing the following processing on at least one sub-echo signal: dividing a sub-echo signal into a second predetermined number of unit echo signals according to the scanning depth, and assigning a weighting coefficient for each unit echo signal (S202); using a corresponding predetermined window function to perform amplitude apodization on each unit echo signal, and using the weighting coefficients corresponding to the unit echo signals to weight corresponding unit echo signals, so as to obtain processed unit echo signals (S204); and forming processed sub-echo signals according to the second predetermined number of processed unit echo signals (S206).
