Color flow imaging plays a major role in the diagnosis of many vascular diseases, especially cardiovascular disease. The imaging quality is highly influenced by the clutter originating from the vascular wall, stationary and slowly moving tissues and relative motion between the probe held by doctor and the blood flow. The clutter rejection filter in front of the mean frequency estimator will restrict...
Color flow imaging plays a major role in the diagnosis of many vascular diseases, especially cardiovascular disease. A novel scheme is proposed to suppress velocity ambiguity induced by the narrowband estimators based on the two-dimensional correlation function model by incorporating with the wideband velocity estimation techniques. The basic idea is that the velocity is first estimated by narrowband...
