Chapter 8 Measurements and Calculations
3 Distance Volume
This is a basic measurement that is available in all diagnosis modes. Measure the volume of an
object by using three straight lines on a 2D image.
1. Select 3 Distance Volume 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. Measure the length of the remaining two straight lines using the same method as above.
3. When the measurement has been taken, the result is shown on the screen. The volume (Vol.)
will be calculated along with the length of each line.
The equations used for 3 Distance measurement are as follows:
, (D: distance)
Ellipse Volume
This is a basic measurement that is available in all diagnosis modes. Measure the volume of a cone-
shaped object by using one circle (ellipse) on a 2D image.
1. Tap Ellipse Volume on the touch screen. Specify the size of the circle (ellipse). This
measurement is taken in the same way as ‘Ellipse’.
2. When the measurement has been taken, the result is shown on the screen.
The following equation is used for Ellipse measurement:
