Blood flow imaging method and ultrasonic imaging equipment

Abstract

The invention discloses a blood flow imaging method and ultrasonic imaging equipment. The method comprises the steps: emitting ultrasonic waves to a target blood flow area along a first scanning angle and a second scanning angle; receiving an ultrasonic echo returned from the target blood flow area to obtain a first ultrasonic echo signal and a second ultrasonic echo signal; performing signal processing on the first ultrasonic echo signal to obtain a first color ultrasound image and a first blood flow velocity; performing signal processing on the second ultrasonic echo signal to obtain a second blood flow velocity; synthesizing the first blood flow velocity and the second blood flow velocity to obtain a vector velocity of blood flow; and displaying the vector velocity of the blood flow and the first color ultrasound image in an overlapping manner. The vector velocity of the blood flow is superposed on the color ultrasound image to be displayed, so that the color ultrasound image printing habit of medical personnel is not changed, the traditional clinical diagnosis is not influenced, more blood flow information provided based on vector blood flow imaging is obtained, and more help is provided for auxiliary diagnosis and treatment of the medical personnel.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of ultrasound imaging and display, and in particular to a blood flow imaging method and ultrasound imaging equipment. Background technique [0002] Color Doppler ultrasound, referred to as color Doppler ultrasound, generally uses autocorrelation technology for Doppler signal processing. The blood flow signal obtained by autocorrelation technology is color-coded and superimposed on the two-dimensional image in real time to form a color Doppler image. Ultrasound blood flow image. Color Doppler ultrasound examination is non-invasive, it can provide rich visual information of blood flow, and is widely used in clinical examination and qualitative analysis in practice. [0003] Traditional color Doppler ultrasound calculates the velocity component of the blood flow along the ultrasonic propagation direction, and the red and blue color spectrum in the color Doppler ultrasound only indicates t...

Problems solved by technology

[0005] However, there are some differences between traditional color Doppler ultrasound imaging and ultrasound vector flow imaging in terms of operation and display. Senior medical personnel are already familiar with the operation of traditional color Doppler ultrasound. Unfamiliar; In addition, the diagnosis of many diseases is based on traditional color Doppler ultrasound. Due to the short development time of ultrasound vector flow imaging, the application of ultrasound vector flow imaging is still in its infancy. Medical personnel may use ultrasound vector flow imaging due to their experience Insufficient results in low efficiency or failure to find key information

Therefore, clinically, medical personnel mostly use traditional color Doppler ultrasound for auxiliary diagnosis, but the obtained blood flow information is relatively little or inaccurate
