Module Description

Calculate a transformation from two input fiducial lists.

This transformation can then be applied to a volume using the Resample Scalar/Vector/DWI Volume module.

Note: renamed from RealignVolume.

Usage

Use Cases, Examples

This module is especially appropriate for these use cases:

  • Use Case 1: place fiducials in two orthogonal lines in a an image to define the midline and the ACPC line
  • Use Case 2:

Examples of the module in use:

  • Example 1
  • Example 2

Quick Tour of Features and Use

  • Transform panel: Calculate a transform from midline and ACPC fiducial lists, and specify an output transform.
    • ACPC Line: a fidicual list containing two fiducial points, one at the anterior commissure and one at the posterior commissure. The resulting transform will bring the line connecting them to horizontal to the AP axis.
    • Midline: pick a fiducial list from the scene that defines the midline. The midline is a series of points defining the division between the left and right hemispheres of the brain (the mid sagittal plane). The resulting transform will put the output volume with the mid sagittal plane lined up with the AS plane.
    • Output transform: An output transform - load the calculated transform in this node.
  • Debug panel: Set debugging flag
    • Debug: click to see print outs
  • Use: the order in which the acpc fiducials are picked is not important.

Development

Notes from the Developer(s)

Ported from Slicer 2.6.

Dependencies

The fiducials module is required for this module's use. The Resample Scalar/Vector/DWI Volume module can be used to apply the transform once it has been calculated.
