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 auto-

matically 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.

 Stenosis Measurement

You can measure the stenosis of each blood vessel system by measuring and calculating an area or dis-

tance.



■

% StA (Stenosis Area)

Measure the area of the inner and outer walls of a blood vessel.

1. Select the %StA menu and the rst cursor will appear in 2D Mode.

2. Measure the area of the vessel’s outer wall using the Circ/Area measurement method.

When the second cursor appears, measure the area of the vessel’s inner wall under stenosis.

%Stenosis Area. = (Outer Area – Inner Area)/Outer Area × 100



■

% StD (Stenosis Distance)

Measure the diameter of a blood vessel.

1. Select the %StD menu and the rst cursor will appear in 2D Mode.

2. Measure the total diameter of a blood vessel using the Distance measurement method.

When the second cursor appears, measure the diameter of the vessel’s inner wall under stenosis.

%Stenosis Dist. = (Outer Distance – Inner Distance)/Outer Distance × 100
