[Dynamic 3D reconstruction of Doppler flow ultrasound medical images].
OBJECTIVE
To implement dynamic 3D reconstruction of ultrasonic flow images by the technique of 3D reconstruction of ultrasonic medical images combined with Doppler flow imaging method.


METHODS
Through analyzing the color-coded mode of Doppler flow images and utilizing the Color Bar in DFI provided by ultrasound system, the information of anatomical structure and blood flow velocity were separated from original DFI images. Then 3D reconstruction of blood velocity and its fusion display with 3D anatomical structure was implemented.


RESULTS
Clinical experiments showed that in vivo blood flow in heart cavity could be shown in 3D space simultaneously with anatomical structure of the heart, and the relationship between them was consistent with cardiology. The images rendered in such a way could show more medical information than that in traditional methods.


CONCLUSIONS
The combination of 3D reconstruction of ultrasonic medical images and Doppler imaging technique could realize functional 3D reconstruction of ultrasonic medical images so as to give more medical information. It would have great potential application and present a new future for ultrasonic medical imaging.
