measure the angle between them.

Select

Angle

in the

Soft Menu

[1]

. Angle will appear in the user information area.

Draw two straight lines. For information on drawing a straight line, please refer to ‘Distance.’

The angle between two lines will be calculated and displayed on the screen.

X When two angles are calculated, the smaller angle is displayed.

 %StD

StD stands for Stenosis Distance, which is a basic measurement available in all diagnosis modes. In a 2D

image, the diameter of a vessel is measured and the stenosis ratio calculated.

Sele

ct %StD in

the

Soft Menu

[1].

%StD will a

ppear in the user information area.

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

When a new cursor appears, measure the inner wall diameter of the vessel under stenosis.

Calculate %StD with the following equation:

X

%StD = (Outer Distance – Inner Distance) / Outer Distance × 100

 M Distance

This is a basic measurement that is available in M Mode only. You can specify two points in an M image and

measure the distance, elapsed time and velocity between them.

Sele

ct M Distance in the

Soft Menu

[1].

M Distance will appear in the user information area.
