(a) Curves demonstrating average simplified pressure gradient and the computed volumetric flow rate through the cerebral aqueduct versus time for patient 2. The respiratory component is more prominent in the flow rate curve. For this patient, the ratio between cardiac and respiratory amplitude was 3.31 for the pressure gradient and 1.27 for the volumetric flow rate. (b) Cardiac peak volumetric flow rate for all patients over all time windows. (c) Respiratory peak volumetric flow rate for all patients over all time windows.
