Module Description

ChangeTracker is a software tool for quantification of the subtle changes in pathology. The module provides a workflow pipeline that combines user input with the medical data. As a result we provide quantitative volumetric measurements of growth/shrinkage together with the volume rendering of the tumor and color-coded visualization of the tumor growth/shrinkage. ChangeTracker is not yet a generic tool for detecting small changes. It has been tuned specifically for meningioma growth analysis. Specifically, the assumptions made by ChangeTracker are the analyzed images are roughly aligned the pathology area is characterized by bright image intensities (contrast-enhanced meningioma MRI) images have similar, close to isotropic, spacing the change in pathology between the consequtive scans is small in relation to the total pathology volume If you want to apply ChangeTracker on non-meningioma data, please let us know. The algorithm is likely to require tuning of the parameters for registration and other processing steps.

Use Cases

Most frequently used for these scenarios:

• Quantification of small changes in meningioma tumor volume from post-contrast MRI

Information for Developers

The section above is generated using the following wiki code:

{{documentation/{{documentation/version}}/module-section|Information for Developers}}
{{documentation/{{documentation/version}}/module-developerinfo|ModuleTemplate|type=Interactive|category=Example}}

If you are documenting a CLI, the category should be extracted from the corresponding XML description. This could be done automatically using the following wiki template:

{{documentation/{{documentation/version}}/module-category|xmlurl=http://path/to/YOURMODULENAME.xml }}

If your module is available in Slicer repository, the following template could be useful to obtain the corresponding URL:

{{documentation/{{documentation/version}}/module-cli-xmlurl|{{documentation/modulename}}|SVNREVISION}}

Using this later template, the final syntax would be:

{{documentation/{{documentation/version}}/module-category|xmlurl={{documentation/{{documentation/version}}/module-cli-xmlurl|{{documentation/modulename}}|SVNREVISION}} }}
