Chapter 5 Measurements and Calculations
Item Type Unit Equation
S/D (Ratio of PSV to EDV) Calculation Ratio (PSV / EDV)
D/S (Ratio of EDV to PSV) Calculation Ratio EDV /PSV
RI (Resistivity Index) Calculation Ratio (PSV – EDV) / PSV
PI (Pulsatility Index) Calculation Ratio (PSV – EDV) / Vmean
Tips!
Taking measurements via Auto Calc
You can use Auto Calc to take measurements on predetermined item(s).
Items measured are as follows. For information on setting measurement item(s), please refer to Auto Calc”
in "Chapter 7. Utility.
Peak Systolic Velocity (PSV)
Time Averaged Mean Velocity (TAMV)
End Diastolic Velocity (EDV)
Diastole / Systole Ratio (D/S)
Time Averaged Peak Velocity (TAPV)
Max Pressure Gradient (PGmax)
Resistive Index (RI)
Mean Pressure Gradient (PGmean)
Pulsatility Index (PI)
Velocity Time Integral (VTI)
Systole / Diastole Ratio (S/D)

Volume Flow Measurement
Select Volume Flow in the Measurement menu.
Volume Flow allows you to measure and calculate an area or distance. For information on distance or
area measurements, please refer to “Basic Measurements. The TAMV (Time Avg. Mean Velocity) value is
automatically measured.
Vesl. Area (Vessel Area)
Measure the area of a blood vessel and calculate TAMV and Volume Flow.
Vesl. Dist. (Vessel Distance)
Measure the width of a blood vessel and calculate TAMV and Volume Flow.
