Measuring Vessel Blood Velocities
When you select PS/ED to measure an arterial velocity, the Terason software calculates
the following measurements:
• Peak Systole
• End Diastole
• Peak Systole/End Diastole ratio (S/D)
• Resistance Index (RI)
You can measure PS/ED for a scan that uses frequency (
kHz
) or velocity (
cm/s
) as the
velocity display units (the Y-axis of the Time Series window).
Complete the following steps to measure the PS/ED values for an artery:
1.
Click
. If playing a loop, click
. The 2D and PWD measure tabs are added to
the Image Control bar.
2.
Click the Rt (right) or Lt (left) button to specify the
Laterality
of the scanned artery.
3.
Click the Prox, Mid, or Distal button to specify the
Location
of the scanned artery.
