Abstract

The invention relates to the technical field of ultrasonic imaging, and discloses a Doppler ultrasonic blood flow automatic identification method. The method comprises the following steps of acquiringmultiple frames of blood flow data signals; carrying out superposing of the multiple frames of blood flow data signals to obtain a superposed signal; performing marking on a connected region with a blood flow signal in the superposed signal, and searching for a maximum connected region; performing filtering on the superposed signal by taking the maximum connected region as a blood flow region; identifying the position information of the blood vessel according to the filtered superposed signal; and setting a sampling frame according to the position information, and performing blood vessel identification according to the sampling frame. The method has the technical effects of automatically identifying the blood vessel, reducing the difficulty of ultrasonic detection operation and quickly and accurately positioning the blood vessel.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to a Doppler ultrasonic blood flow automatic identification method, device and computer storage medium. Background technique [0002] Color Doppler Flow Imaging (CDFI) is a diagnostic technique for cardiovascular diseases that has come out in recent years. The rapid, intuitive and convenient display mode of CDFI has opened up a new way for the study of hemodynamics. It is widely used in vascular diseases, abdominal organs, small organs, obstetrics and gynecology and other departments. [0003] Color Doppler applies the Doppler effect. The basic principle is to use the frequency change caused by the movement between the sound wave source or the sound wave receiver, and the generation of frequency shift. In medical ultrasonography, the sound waves emitted by the probe on the ultrasonic instrument enter the blood vessels of the human body, and the red blood cells, the mai...
