Module Description

Mutual information based affine registration using a multi-resolution optimization strategy.

Usage

Examples, Use Cases & Tutorials

Quick Tour of Features and Use

List all the panels in your interface, their features, what they mean, and how to use them. For instance:

  • Required:
    • Fixed Image - Target image for registration. The resulting transform will map the moving image to the fixed image.
    • Moving Image - Source image for registration. The resulting transform will map the moving image to the fixed image.
    • Resample Image - Image node to create a resampled moving image. The image node specified in this transform will store the result of resampling the moving image with computed transform. Typically the user should select to create a new volume here. This does not need to be specified, but the user should select either this option or output transform.
    • Output Transform - Store the result of the transform in the given transform node. Typically the user should select to create a new transform node.
  • Optional:
    • Fixed Image Mask Image - A label image that is used to mask regions of interest in the fixed image. The mask specified here is used to restrict the placement of samples in the fixed image used for optimizing the registration. The user may want to mask the brain from background, mask everything in the brain except a lesion region, or otherwise specify the regions they would like to optimize in the registration.
  • Advanced:
    • Number of iteration - Number of iterations to run at each stage of the optimization. This method uses Fletcher-Reeves-Polak-Ribiere optimizer and the number of 1-D optimization is bounded by the number of iterations times the dimensionality of the transform.
    • Number of line iterations - Number of iterations to use in the 1-D line optimization. This is used to bound the maximum number of iterations that can be used in the 1-D optimization at each iteration of the optimization .
    • Step size - Maximum step size of each iteration of the transform. The optimizer computes a 1-D minimum along the gradient direction that is bounded by the current location and this distance. This should be specified in terms of voxels.
    • Step Tolerance - Minimum step size to continue optimization. When the 1-D minimization bounds the minimum within this tolerance, the optimizer moves to the next iteration.
    • Metric Tolerance - When steps of the optimizer result in changes in the metric value less than this, the optimization stops and the current result is returned.

Development

Dependencies

  • Editor, Threshold, Segmentation module: Useful for computing a label mask for the 'Fixed Image Mask Image' option.
