Module Description
This is the plastimatch landmark-based deformable image registration module. The intended application of this method is rapid, interactive correction of registration failures with a small number of mouse clicks. Compared to other landmark-based methods, the plastimatch registration method might offer:
- both local and global registration
- regularization of the deformation field
Examples of how this module is being used:
- Intra-subject registration for adaptive radiotherapy
- Inter-subject registration for automatic segmentation
Usage
Tutorials
Quick Tour of Features and Use
- Input/Output panel:
- Fixed Volume: Here you choose the "fixed image", which is the reference image.
- Moving Volume: Here you choose the "moving image", which will be warped to match the fixed image.
- Output Volume: Here you choose where to put the warped image. You can replace an existing image in the scene, or create a new image.
- Basis function: Here you can choose either tps (thin plate splines), or gauss (Gaussian RBF), or wendland (Wendland RBF).
- RBF radius: Here you can choose the radius of RBF.
- Stiffness: Here you can choose the regularization parameter.
- Default Pixel Value: Here you can choose the value for pixels with unknown value.

More Information
About plastimatch
Plastimatch is an open source software for deformable image registration. It is designed for high-performance volumetric registration of medical images, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). Software features include:
- B-spline method for deformable image registration (GPU and multicore accelerated)
- Demons method for deformable image registration (GPU accelerated)
- ITK-based algorithms for translation, rigid, affine, demons, and B-spline registration
- Pipelined, multi-stage registration framework with seamless conversion between most algorithms and transform types
- Landmark-based deformable registration using thin-plate splines for global registration
- Landmark-based deformable registration using radial basis functions for local corrections
- Broad support for 3D image file formats (using ITK), including Dicom, Nifti, NRRD, MetaImage, and Analyze
- Dicom and DicomRT import and export
- XiO import and export
- Plugins for 3D Slicer
Plastimatch also features two handy utilities which are not directly related to image registration:
- FDK cone-beam CT reconstruction (GPU and multicore accelerated)
- Digitally reconstructed radiograph (DRR) generation (GPU and multicore accelerated)
