Embodiment 1

[0063] Please refer to figure 1 , figure 1 This is a flowchart of an ultrasound Doppler blood flow imaging method in the embodiment of the application, and the method includes the following steps:

[0064] S101. Acquire an orthogonal analytical signal to be subjected to ultrasound Doppler blood flow imaging.

[0065] Wherein, the quadrature analysis signal includes tissue signal and blood flow signal.

[0066] Among them, the orthogonal analysis signal is the signal obtained by analyzing the detected echo after the ultrasonic wave is emitted from the part to be tested. There are tissue signals as well as blood flow signals. In particular, in the blood flow signal, a forward blood flow signal and / or a reverse blood flow signal may also be included. That is, the blood flow signal may only have a blood flow signal in one direction, such as forward or reverse, or may include blood flow signals in both forward and reverse directions. When there are blood flow signals in two di...

Abstract

The present application discloses an ultrasonic Doppler blood flow imaging method, device, equipment and a readable storage medium. The orthogonal analysis signal is filtered to obtain the target blood flow signal in the specified direction; the target blood flow signal is processed to obtain the blood flow velocity; and the blood flow velocity is used for ultrasonic Doppler blood flow imaging processing. In the method, a complex wall filter is used to process the orthogonal analytical signal to be subjected to blood flow imaging, so as to obtain a more accurate and direction-specific blood flow signal. When calculating the blood flow velocity, the blood flow velocity can be calculated and imaged based on the direction. In this way, even when there are both positive blood flow signals and reverse blood flow signals, the problem that the blood flow velocity and the blood flow direction cannot be displayed due to the average velocity being 0 will not occur.

Description

technical field [0001] The present application relates to the technical field of ultrasound imaging, and in particular, to an ultrasound Doppler blood flow imaging method, apparatus, device, and readable storage medium. Background technique [0002] One of the most important functions of current medical ultrasound imaging equipment / systems is ultrasound Doppler blood flow imaging. Ultrasound Doppler blood flow imaging can observe the blood flow distribution and hemodynamic distribution of the measured tissue or organ in real time, thus providing an important basis for doctors to identify and diagnose tissue physiological and pathological states. [0003] Specifically, ultrasound Doppler blood flow imaging can provide the velocity and direction of blood flow at any sampling position or sampling volume in any specific two-dimensional slice or three-dimensional volume data in real time. It should be noted that at present, for any sampling position or sampling volume, the blood...
