Module Description
Overview of what the module does goes here.
Usage
- Parameters:
- Iterations: Number of iterations to run the optimization method to estimate the registration parameters.
- Grid Size: Number of grid points on interior of the fixed image. Larger grid sizes allow for finer registrations.
- You can use this module to manually run a multiresolution registration by starting with a coarse grid, creating a resampled volume, and passing that resampled volume as the moving image for the next run with a finer grid.
- Make sure you hit the tab key when changing the grid size.
- Histogram bins: Number of histogram bins to use for Mattes Mutual Information. Reduce the number of bins if a deformable registration fails. If the number of bins is too large, the estimated PDFs will be a field of impulses and will inhibit reliable registration estimation.
- Spatial samples: Number of spatial samples to use in estimating Mattes Mutual Information. Larger values yield more accurate PDFs and improved registration quality.
- Constrain deformation: Constrain the deformation to the amount specified in Maximum Deformation
- Maximum deformation: If Constrain Deformation is checked, limit the deformation to this amount.
- Default pixel value: Default pixel value used if resampling a pixel outside of the volume.
- IO
- Intial Transform: Initial transform for aligning the fixed and moving image. Maps positions in the fixed coordinate frame to positions in the moving coordinate frame. This transform should be an affine or rigid transform. It is used an a bulk transform for the BSpline. Optional.
- Fixed image: Fixed image to which to register
- Moving image: Image to register to the fixed image
- Output transform: Transform calculated that aligns the fixed and moving image. Maps positions from the fixed coordinate frame to the moving coordinate frame. Optional (specify an output transform or an output volume or both).
- Output Volume: Resampled moving image to fixed image coordinate frame. Optional (specify an output transform or an output volume or both).

- Be careful how you set the parameters
