Abstract

The invention provides a Doppler frequency spectrogram generating method and device. The Doppler frequency spectrogram generating method comprises the steps of obtaining M-wave characteristic data, identifying blood flow data in the M-wave characteristic data, determining the depth corresponding to a Doppler frequency spectrogram according to the blood flow data and generating the Doppler frequency spectrogram based on the determined depth. The Doppler frequency spectrogram generating method and device can automatically generate the ideal Doppler frequency spectrogram without intervention from a user, the working intensity of the user is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a method and equipment for generating a Doppler spectrogram. Background technique [0002] The Doppler effect is the change in the wavelength of waves radiated by an object due to the relative motion of the object and the observer. In front of the moving wave source, the wave is compressed, the wavelength becomes shorter and the frequency becomes higher; when behind the moving wave source, the opposite phenomenon occurs, the wavelength becomes longer and the frequency becomes lower. The higher the motion speed of the wave source, the more significant the Doppler effect will be. Therefore, according to the extent to which the wave frequency changes, the speed at which the wave source moves along the direction of observation can be calculated. [0003] Doppler ultrasound blood flow analysis is a method to evaluate different physiological characteristics through non-invasive...
