Basic Measurements
13.4 Volume Measurements
There are four methods in which to measure the Volume of structures of different shapes.
1. To measure the volume of an ovoid using three distances (axis).
2. To measure the volume of the ovoid using one distance and ellipse.
3. To measure the volume of a globe using one distance (diameter).
4. To measure the volume in the 3D mode with the 3D MultiPlane method.

to return to the scan mode and scan the structure transverse to the first scan.
Press
[

]
again. A new cursor appears.
Note: If you have scanned the second image in Dual mode previously, you can measure the third
distance within the second image.
6. Perform the measurement of the third distance in the same manner.
Remarks:
•
The Volume of the ovoid measured by three distances is displayed.
