In order to ensure the accuracy of ultrasonic Doppler inspection, the imaging parameters of the image need to be adjusted artificially and professionally during the entire inspection process, which puts forward high professional requirements for the user's professionalism, and the complete adjustment process steps Extremely complex, with high professional requirements for user concentration

This has resulted in the need to adjust the parameters of the ultrasonic Doppler system device every time the user performs the ultrasonic Doppler system detection process, and the judgment of the results during the ultrasonic examination process is mostly related to the doctor's skills and experience, reducing the System Ease of Use

[0003] The patent application document with the application number 201810005469.2 discloses a Doppler blood flow velocity imaging method and system based on ultrasound channel data, which can separately estimate the blood flow velocity through the channel data corresponding to different array elements, and then through the angle phase Alignment and superposition can improve the signal-to-noise ratio of the blood flow signal, thereby improving the accuracy of blood flow velocity estimation, but it cannot accurately mark and distinguish the blood vessel area, which is not conducive to the auxiliary diagnosis of the exact disease

[0004] The patent application document with the application number 201510670863.4 discloses a method for automatic optimization of ultrasound spectrum Doppler, which can adjust the angle, and at the same time can automatically and roughly identify the direction of blood flow, thereby reducing the cost of optimizing the adjustment parameters of ultrasound spectrum images time, reduce the doctor's operating burden, and improve work efficiency, but cannot accurately mark and distinguish the vascular area, which is not conducive to the auxiliary diagnosis of the exact disease
