The real-time Doppler color flow mapping (CFM) technique has proven to be extremely useful in everyday clinical practice of adult and pediatric cardiology.'-3 The rapid assessment of valvular regurgitation and congenital lesions such as ventricular septa1 defects and patent ductus arteriosus are now possible. The availability of new information in the form of color patterns representing spatially distributed blood flow velocities superimposed on the real-time two-dimensional image of the heart has formed a basis for this new diagnostic modality. The initial qualitative and semiquantitative color jet interpretations focused on the measurements of color jet shapes and lengths. These were based on the studies of disturbed flow areas and the assumption that the size of a jet flow abnormality is proportional to its severity: Jet length and area ratios were the first semi-quantitative color flow mapping applications for the assessment of the severity of valvular disease.'-' The cardiac output calculation from color Doppler was also explored! Recent availability of color image processing technology and application of specific algo-r i t h m ~ ~ have led to the quantification of color-encoded spatial jet velocities and velocity profiles. Color image processing is a new technique that provides objective insight into the color encoding of blood flow patterns by CFM instruments. Due to the limitations of current CFM technology, the direct clinical applications of CFM quantification are still in their infancy.
