Module Description

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)

Usage

Use Cases, Examples

Plastimatch contains three separate plugins

• Automatic (B-spline) deformable image registration

Compared to other methods, the plastimatch registration method probably offers (1) superior accuracy for CT-CT registration, and (2) faster results. However, the plastimatch transform is not compatible within the MRML scene, so you cannot easily use it together with other plugins.

• Manual (landmark) deformable image registration

If you need to manually adjust your registration results, this is the tool for you! You can define a small number of corresponding landmarks (as few as one or two) to repair minor misregistrations. However, the plastimatch transform is not compatible within the MRML scene, so you cannot easily use it together with other plugins.

• DICOM-RT structure set import

This handy plugin will load a DICOM-RT structure set, and render it as a labelmap.

Examples of the module in use:

• Intra-subject registration for adaptive radiotherapy
• Inter-subject registration for automatic segmentation
