Cancer Imaging Phenomics Toolkit (CaPTk)  1.8.0.Beta
Image Co-registration

This tool registers multiple moving images to a single target image using the Greedy Registration technique [1].

REQUIREMENTS:

  1. A Target image.
  2. Up to 5 moving images

USAGE:

  1. Launch the "Registration" dialog from the "Preprocessing" menu.
  2. Customize the parameters (Metrics, Radius and Iterations) as needed; for details regarding the parameters and their usage, please refer to the Greedy manual [2].
  3. Specify the moving images (up to 5) and their respective output images.
  4. Click on 'Register'.
  5. The output image is saved in the specified locations.
  6. This can also be used from the command line:
    ${CaPTk_InstallDir}/bin/Preprocessing.exe -i moving.nii.gz -rFI fixed.nii.gz -o output.nii.gz -reg Affine -rME NCC-2x2x2 -rIS 1 -rNI 100,50,5
    

More usage options are available via the greedy command-line executable (see documentation for it here), which is present in ${CaPTk_InstallDir}/bin/.
