Chapter 8 Measurements and Calculations
Ellipse + Dist. Vol.
This is a basic measurement that is available in all diagnosis modes. Measure the volume of an object
by using one straight line and one circle (ellipse) on a 2D image.
1. Tap Ellipse + Dist Vol. on the touch screen. Specify the size of the circle (ellipse). Measurement is
taken in the same way as ‘Ellipse’.
2. Specify two points and measure the length of the straight line between the points. Measurement is
taken in the same way as ‘Distance’.
3. When the measurement is nished, its result is shown on the screen.
The equation for measuring ‘Ellipse+ Dist Vol.’ is as follows:

Disk Volume
This is a basic measurement that is available in all diagnosis modes. Calculate the volume of an
irregularly shaped object by measuring the area and the length of its long axis on a 2D image.
1. Select Disk Volume on the monitor or touch screen. Draw the contour of the area to be measured.
Measurement is taken in the same way as ‘Trace’.
2. Measure the length of the long axis. Measurement is taken in the same way as ‘Distance’.
3. When the measurement is nished, its result is shown on the screen.
Tips!
Editing Curves
Before specifying the end point by pressing the Set button, you can delete part of the curve being
traced by rotating the soft menu dial-button 5 counter-clockwise.
