Measurement Process
The measurement process consists of three steps: region definition, checking of the validity of the
regions, and feature calculation.
Region definition:
- Automatically from the mask image
Region validation check depends on:
- Minimum volume
- Measurement condition
Feature calculation depends on
- Shape of the region
- Densitometric value distribution of the region
- Feature parameters

All regions found are checked according to certain conditions. The voxel volume of each region must be
equal to or greater than
MinVolume
. The measurement condition must be fulfilled. Only those regions
that meet all the conditions are valid for the measurement. The region can be measured or labeled.
Measurement is a process that produces data. Labeling is a process that generates an image volume.
