Chapter 8 Measurements and Calculations

 %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 blood 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 using the following equation:

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

 Distance(M)

This is a basic measurement that is only available in M mode. Specify two points on an M image,

and measure the distance between the two points

1. Select Distance (M) on the monitor or touch screen. Specify two points and measure the length

of the straight line between the points. This measurement is taken in the same way as ‘Distance’.

2. When the distance has been measured, the result is shown on the screen.

 Slope

This is a basic measurement that is only available in M mode. Specify two points on an M image,

and measure the velocity between the two points

1. Select Slope on the monitor or touch screen.

2. Specify two points and measure the length of the straight line between the points. This

measurement is taken in the same way as ‘Distance’.

3. When the distance has been measured, the result is shown on the screen.
