Distance + Ellipse
This is a basic measurement available in all diagnosis modes. You can measure the volume of an object
in a 2D image by using one straight line and one circle (ellipse).
1. Press the Caliper button and select Distance + Ellipse in soft menu [3]. “Distance + Ellipse” is
displayed in the user information area.
2. Specify two points and then measure the shortest distance between them. The measurement
method is the same as in ‘Distance.’
3. Set the size of the ellipse. The measurement method is the same as in ‘Ellipse’.
4. Once measurement is taken, the result is displayed on the screen.
X D: Length of the straight line
X Long: Length of the long axis in the ellipse
X Short: Length of the short axis in the ellipse
X Area: Area of the circle
X Vol.: Volume
The following formula is used for Distance + Ellipse measurements:

Ellipse
This is a basic measurement available in all diagnosis modes. In a 2D image, the volume of a conical
object is measured using an ellipse.
1. Press the Caliper button and select Ellipse in soft menu [3]. Ellipse will appear in the user
information area.
2. Set the size of the ellipse. The measurement method is the same as in ‘Ellipse’.
3. Once measurement is taken, the result is displayed on the screen.
The following formula is used for Ellipse measurements:
