Patent ID: 8480590

Claim:
A computer-implemented method comprising: acquiring color Doppler data; detecting one or more transitions of the color Doppler data, each of the one or more transitions being between a first area representing flow velocity in a first direction and a second area representing flow velocity not in the first direction; evaluating a normalized energy function across one or more of the one or more transitions; determining, for each flow area of the color Doppler data, whether the flow area is in contact with a zero velocity area, and whether the flow area is surrounded by and in contact with a flow area of opposite velocity direction; and determining an aliasing correction for each respective flow area of the color Doppler data based on the evaluated normalized energy functions, and based on the determination of whether the respective flow area is in contact with a zero velocity area, and the determination of whether the respective flow area is surrounded by and in contact with a flow area of opposite velocity direction.
