Abstract
The present disclosure relates to a method for determining blood flow velocity using a dual die group and a Doppler blood flow detection device including a first die group and a second die group placed at different positions of a blood vessel to be detected. The method includes obtaining a first spectrum waveform by detecting the blood vessel to be detected using the first die group, obtaining a second spectrum waveform by detecting the blood vessel to be detected using the second die group, determining a relationship between an actual Doppler angle during detection and a set Doppler angle in the Doppler blood flow detection device according to the first spectrum waveform and the second spectrum waveform, adjusting the first spectrum waveform and the second spectrum waveform according to the determined relationship, and determining a blood flow velocity measurement value based on the adjusted first and second spectrum waveforms.
