Abstract :
The application of 2D color flow Doppler techniques to the detection and diagnosis of cardiac and vascular abnormalities is currently limited by two factors. First, the difficulty in extrapolating multiple 2D images into 3D space, and second, by the inaccurate color flow data provided. The authors are developing 3D reconstruction techniques to display color flow data which has been corrected for the angular error between the orientation of the Doppler beam and the central axis of the flow field. This methodology is currently being applied to the carotid artery, and is being developed for both experimental and clinical settings
