Chapter 5.Measurements and Calculations 5 - 17

▐ 2D Trace

This is a basic measurement that is available in all diagnosis modes. You can measure the

circumference and area of an irregular object in a 2D image.

You can measure up to 4 distances. When taking more than one measurement, use

measurement cursors with different shapes (+, X, #, *) to differentiate them.

1. Select the Flexible Soft button [2] Trace. “2D Trace” is displayed in the user

information area.

2. Use the Trackball and the Set button on the control panel to specify the start point for

tracing over the contour of the measurement area.

- Place the cursor at a desired position with the Trackball, and press the Set button.

3. Trace the curve so that the measurement cursor returns to the start point, and then

press the Set button.

NOTE

Trace lines must be closed. If you press the Set button before tracing

is complete, tracing may be done over a straight line between the

current point and the start point, resulting in a significant error.

4. When the measurement is finished, its result is shown on the screen.

- Circ.: Circumference of Object

- Area: Area of Object

- Avg.(C): Average Circumference

- Avg.(A): Average Area

5. A new measurement cursor appears. When more than 4 straight lines are specified,

the lines are deleted in the order in which they have been specified.

The equations used for Trace measurement are as follows:

( ) ( ){ } ( ) ( ){ }
