Method, device and equipment for ultrasonic Doppler blood flow imaging and readable storage medium

Abstract

The invention discloses a method, device and equipment for ultrasonic Doppler blood flow imaging and a readable storage medium. The method comprises the following steps: acquiring an orthogonal analysis signal to be subjected to ultrasonic Doppler blood flow imaging; filtering the orthogonal analysis signal by utilizing a complex-wall filter to obtain a target blood flow signal in a specified direction; processing the target blood flow signal to obtain a blood flow motion speed; and performing ultrasonic Doppler blood flow imaging processing by utilizing the blood flow motion speed. In the method, the complex-wall filter is utilized to process orthogonal analysis signals to be subjected to blood flow imaging, so that more accurate blood flow signals in a specified direction can be obtained, so that during calculation of the motion velocity of a blood flow, the motion velocity of the blood flow can be calculated and imaged based on the direction. Therefore, even when both a positive blood flow signal and a reverse blood flow signal exist, the problem that the blood flow velocity and the blood flow direction cannot be displayed due to the fact that the average velocity is zero does not occur.

Description
