Description

technical field [0001] The invention relates to fluid information imaging and display technology in an ultrasonic system, in particular to a three-dimensional 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 wi...

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.
