ABSTRACT:
Velocity data is automatically anti-aliased. Since a tissue velocity varies a small amount over small distances, more accurate velocity or strain rate estimates are calculated automatically with an anti-aliasing algorithm. Since the velocity information derived from phase information, like Doppler, contains uncertainties of a multiple of a specific velocity (e.g., a constant multiple of 2π error), a specific velocity is at least one of multiple possible velocities. The possible velocities are calculated and the specific velocity selected. Additional velocities may then be extrapolated for different regions or subsequent frames of data for a same region.
