Abstract
With the introduction of two-dimensional color Doppler flow mapping, a unique approach to imaging velocity fields in the cardiac chambers and blood vessels has become available. The aim of this study was to evaluate the effect of different wall motion filters on the accuracy of the velocity information obtained by color Doppler flow mapping. We studied the impact of wall filtering on the color coded velocity display both numerically and experimentally. We also analyzed the accuracy of the displayed color Doppler velocities in reconstructed flow profiles across a vessel. This is of importance when color Doppler flow mapping is being used to calculate volumetric flow rate in blood vessels or calculate shear stress at vessel walls.
