General Calculations
Stroke Volume Ratio (SV) (cont'd)
A cross-point cursor appears in the B-Mode image to measure
FCA.
Use the Trackball to move the cursor to a point on the vessel
wall.
Press Set to fix the start point cursor. Use the Ellipse or Trace
method to measure the circumference and area of the vessel as
described on 7–8 or 7–10 , respectively.
Press Set to complete the circumference/area measurement.
The FCA (Flow Cross Sectional Area) is displayed.
The SV (Stroke Volume) is also computed and displayed from
velocity and FCA values.
Automatic SV calculation
If velocity was previously measured while in Doppler Mode and
the cross sectional area of a vessel was measured while in
B-Mode, stroke volume will be automatically calculated from
these previously measured values when SV is selected from
the General Calculation Sub-Menu.
