Fig 3. Time-resolved 3D particle traces in 4 consecutive systolic timeframes illustrate the filling of the right carotid siphon. Note the complex and counter-clockwise helical flow pattern (if viewed along the flow direction) in the C5 segment (open arrow). The emitter plane from which particle traces were released from equidistant grid points is indicated by the solid white arrow. In the superior sagittal sinus (asterisk), particle traces demonstrate lower flow velocities and thus reduced tracer length compared with arterial blood flow.
