Module Description

Create and edit transformations.

Usage

The Transforms module is used for interactive editing of Transformation nodes. Transformation nodes are used in Slicer to define spacial relationships between different nodes (such as volumes, models, fiducials, ROI's, or other Transform nodes) or between the nodes and the global RAS space. You can establish the spacial relations by dragging the nodes under the Transformation nodes in the Data module.

Using Transforms module you can performs the following actions:

• Load transformations from the file. The file format is the ITK transformation

file format.

• Create new Transformation Nodes.
• Select existing Transformation Nodes for editing.
• Edit individual elements of the 4 by 4 transformation matrix.
• Specify the LR, PA, and IS translation components (mm).
• Specify the LR, PA, and IS rotation angles (degrees).
• Switch between different coordinate frames: local or global.
• Set the transformation matrix to identity.
• Invert the transformation matrix.
