Pulse Wave (PW) or Spectral Mode displays the velocities of blood cells in a section of a vessel defined by the green gate lines and at an angle pf the purple dotted line. Blood flow can be examined for unidirectional or laminar flow or may have an opposite direction component which can indicate turbulence. In this mode the gate width and position may be varied and the angle of the sampling may also be varied.
