 Open Spline

This is a basic measurement that is available in all diagnosis modes. Specify multiple points on a 2D

image to measure the length of the resulting Open Spline curve.

1. Select Open Spline on the monitor or touch screen. Use the trackball and the Set button on the

control panel to specify as many points as desired. After specifying the last point of the Open Spline,

press the Set button twice to nish measuring the Open Spline.

X

At least three points must be specified before the Open Spline can be measured.

2. The length of the Open Spline curve created with the points you have specied will be calculated

and displayed on screen.

 Angle

This is a basic measurement that is available in all diagnosis modes. Specify two straight lines on a 2D

image to measure the angle between the two lines.

1. Select Angle on the monitor or touch screen. Draw two straight lines. Refer to ‘Distance’ for

instructions on how to draw a straight line.

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

X

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

 % Stenosis (D)

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

diameter of a blood vessel is measured on a 2D image to calculate its stenosis ratio (%).

1. Select % Stenosis (D) on the monitor or touch screen.

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

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

4. Calculate %StD with the following equation:

%Stenosis (D) = (Outer Distance – Inner Distance) / Outer Distance x 100
