Aliasing doppler artifact

    Can be visualized in the doppler modes(PW, CW, CFM) when velocity is higher than scale of graph. In this case the part of curve(or color in CFM) which not fit the scale moved to the opposite side of the graph(or change color to opposite in CFM)! So to correct this artifact you should increase PRF(if it possible) or use CW(if you used PW because CW has maximum scale).
