Problems solved by technology

This technology requires the doctor to constantly adjust the deflection direction of the ultrasonic beam according to the direction of the blood flow, thus increasing the doctor's workflow, and sometimes it is difficult to judge the direction of the blood flow from the two-dimensional map (easy to misjudge), the doctor can only use the All the deflection directions are traversed to find the optimal sound velocity deflection angle, the operation is more cumbersome

Abstract

The invention provides a method and system for realizing automatic deflection of a spectral Doppler angle. The method comprises the following steps: configuring ultrasound scanning lines of a plurality of scanning angles; transmitting the ultrasound scanning lines to a tissue to be detected; acquiring back wave data corresponding to each deflection angle; carrying out fast Fourier transform on the back wave data of each deflection angle in a pulse repetition frequency domain; and determining the deflection angle corresponding to the maximum value in each energy to be a best angle needed to be deflected in ultrasound scanning. With the adoption of the method and the system, the condition that at least one transmitting wave beam at one direction is not vertical to a bleeding direction can be satisfied through configuring transmitting wave beams of a plurality of deflection angles, an optimum deflection angle can be automatically acquired, so that automatic deflection of the spectral Doppler angle can be realized through the optimum deflection angle; and the sensitivity of spectral Doppler is improved. With the adoption of the method and the system, the working process of doctors can be simplified, and the operation is convenient.

Description

Technical field [0001] The invention relates to the field of medical ultrasound imaging, in particular to a method and system for realizing automatic deflection of spectrum Doppler angle. Background technique [0002] Spectrum Doppler imaging technology and color Doppler imaging technology are the two most important methods in the field of blood flow imaging. Color Doppler imaging technology can provide intuitive blood flow distribution, but lacks the ability to quantitatively analyze blood flow velocity; spectral Doppler imaging technology can accurately and quantitatively detect blood flow velocity, so spectral Doppler imaging technology It is widely used in blood flow detection. [0003] For spectral Doppler imaging technology, it relies on the Doppler effect. When the direction of the ultrasound beam is perpendicular to the direction of blood flow, according to the Doppler effect, the Doppler frequency deviation is almost zero at this time. Therefore, in this case, the sensi...
