Module Description

The DoseComparison module computes the difference between two co-registered dose volumes using the gamma dose distribution comparison method. This module uses the gamma Plastimatch algorithm internally.

Use Cases

Comparing dose distributions

Panels and their use

• Current contour(s): Currently selected contour node (vtkMRMLContourNode) or conotur hierarchy node (vtkMRMLContourHierarchyNode)
• Active representation: The active representation (Ribbon model / Indexed labelmap / Closed surface model) of the selected contour. If a hierarchy is selected in which the active representations of the contained contours do not match, Various is indicated
• Change active representation: This box contains controls to convert from one representation to another
