document: A new high resolution color flow system using an eigendecomposition-based adaptive filter for clutter rejection We present a new signal processing strategy for high frequency color flow mapping in moving tissue environments . A new application of an eigendecomposition-based clutter rejection filter is presented with modifications to deal with high blood-to-clutter ratios -LRB- BCR -RRB- . Additionally , a new method for correcting blood velocity estimates with an estimated tissue motion profile is detailed . The performance of the clutter filter and velocity estimation strategies is quantified using a new swept-scan signal model . In vivo color flow images are presented to illustrate the potential of the system for mapping blood flow in the microcirculation with external tissue motion
