{|
|
Intensity Difference Metric can be used to quantify the differences between the two images. The assumptions made by this metric are that:
* the images are aligned and the major source of difference is due to the anatomical changes of the structures
* the changes are small
|[[Image:Slicer4_IntensityDifferenceMetric.png|thumb|450px|IntensityDifferenceMetric change quantification results]]
|}


{{documentation/{{documentation/version}}/module-section|Use Cases}}
Most frequently used for these scenarios:
* This metric is used in the last step of processing by [[Documentation/4.0/Modules/ChangeTracker|ChangeTracker]].
