Ultrasonic fluid imaging method and ultrasonic fluid imaging system

Abstract

An ultrasonic fluid imaging method and an ultrasonic imaging system. The system comprises: a probe (1); a transmission circuit (2) for exciting the probe to transmit body ultrasonic beams to a scanned target; a receiving circuit (4) and a beamforming module (5) for receiving an echo of the body ultrasonic beams to obtain a body ultrasonic echo signal; a data processing module (9) for obtaining, according to the body ultrasonic echo signal, fluid velocity vector information and three-dimensional ultrasonic image data of a target point inside the scanned target; and a spatial three-dimensional display apparatus (8) for displaying the three-dimensional ultrasonic image data to form a spatial three-dimensional image of the scanning target, and superposing the fluid velocity vector information on the spatial three-dimensional image. The system provides a better multi-angular observation view for a user by means of a 3D display technique.

Description

technical field [0001] The invention relates to fluid information imaging and display technology in an ultrasonic system, in particular to an ultrasonic fluid imaging method and an ultrasonic imaging system. Background technique [0002] In medical ultrasound imaging equipment, common fluid display technologies are only based on the display of two-dimensional images. Taking blood flow imaging as an example, ultrasonic radiation is radiated into the object to be inspected. Like pulse wave and continuous wave Doppler, color Doppler blood flowmeter also uses the Doppler effect between red blood cells and ultrasonic waves to realize imaging. . Color Doppler flowmeter includes two-dimensional ultrasound imaging system, pulse Doppler (one-dimensional Doppler) blood flow analysis system, continuous wave Doppler blood flow measurement system and color Doppler (two-dimensional Doppler) ) blood flow imaging system. The oscillator generates two orthogonal signals with a phase differ...

AI Technical Summary

Problems solved by technology

Two-dimensional ultrasound scanning can only reflect the size and direction of blood flow velocity on the scanning plane

The display technology based on two-dimensional ultrasound images cannot truly reproduce the flow of fluid in any tubular or fluid-storage organs such as blood vessels. The display technology based on two-dimensional images is often isolated in several sections, or through several sections However, the reproduced pseudo-3D images cannot provide doctors with more, more comprehensive and accurate detection image information.
