The module ImageStatistics computes some statistics of the input image voxels.
A subset of voxels is selected depending on the voxels' grey values and a grey value interval (inner interval) defined by the parameter fields Min and Max.
To support the analysis of partial volume effects, two additional, adjacent intervals can be defined by the parameter fields Lower and Upper. Hence, the statistical information is computed for the following subsets:
- Total: all input voxels
- Inner: voxels within the inner interval
- Outer: voxels outside the inner interval
- Lower: voxels within the lower adjacent interval
- Upper: voxels within the upper adjacent interval
On each interval the number of voxels, the corresponding volume, the minimum and maximum values, the mean value and the mean of the absolute voxel values, the variance, the standard deviation and the bounding box (in X, Y, Z, C, T, and U) are calculated.
The computation is either applied to the complete input image, or - if Per Slice is checked - to the slice specified by the Current Slice field.
If a second input image is provided, activating the Use Mask Image setting restricts the computation to voxels for which the corresponding value in the second image is non-zero.
In the lower and upper adjacent intervals the evaluation of partial volume effects is supported by weighting voxels with their distance to the inner interval.
The weighted voxel count is displayed as Weight in the results section. This value can be interpreted as the statistical contribution of the partial volume effect to the number of voxels in the inner interval.
Sets the lower voxel value if the module should work on an interval mask.
Sets the upper voxel value if the module should work on an interval mask.
If pressed, the information fields are being updated.
If checked, the module updates its information fields on each parameter or input image change.
If checked, the module computes the statistical information only on slice specified in Current Slice.
Sets the number of the slice the module should compute information for.
