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...

Embodiment Construction

[0071] figure 1 It is a schematic structural block diagram of an ultrasound imaging system according to an embodiment of the present invention. Such as figure 1 As shown, the ultrasound imaging system generally includes: a probe 1 , a transmitting circuit 2 , a transmitting / receiving selection switch 3 , a receiving circuit 4 , a beamforming module 5 , a signal processing module 6 , an image processing module 7 and a display device 8 .

[0072] During the ultrasonic imaging process, the transmitting circuit 2 transmits the delayed-focused transmitting pulse with a certain amplitude and polarity to the probe 1 through the transmitting / receiving selection switch 3 . The probe 1 is excited by the transmitted pulse, and transmits ultrasonic waves to the scanning target (for example, organs, tissues, blood vessels, etc. in the human body or animal, not shown in the figure), and receives the ultrasonic waves reflected from the target area after a certain delay. Scans the ultrasoni...
