Chapter 5 Measurements and Calculations
5-19
Distance + Ellipse
This is a basic measurement that is available in all diagnosis modes. You can measure the volume of an ob-
ject in a 2D image by using one straight line and one circle (ellipse).
You can measure up to 2 sets of volumes. When measuring more than one set, use measurement cursors
with dierent shapes to dierentiate them.
1. Use the Softmenu switch [3] Volume to select 3D Volume: Distance + Ellipse. “3D Volume: Distance
+ Ellipse” is displayed on the left side of the screen.
2. Specify two points and measure the straight distance between them. The method for measuring a
line is the same as in “2D Distance (Line).
3. Specify the size of the circle (ellipse). The method for measuring a circle (ellipse) is the same as in “2D
Ellipse.
4. When the measurement is nished, its result is shown on the screen.
D: Length of Straight Line
A: Length of A-axis in Ellipse
B: Length of B-axis in Ellipse
V: Volume of Circle (Ellipse)
The equations used for Distance + Ellipse measurement are as follows:

NOTE: Since Dual Mode simultaneously displays two images on the screen, you don’t have to return
to the diagnosis mode to measure volume in Dual Mode.
