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)
+
This is the plastimatch automatic (B-spline) deformable image registration module.  It includes a multi-stage, multi-resolution pipeline, as well as multicore and GPU acceleration.  Compared to other B-spline methods in 3d slicer, the plastimatch registration method might offer:
−
* Digitally reconstructed radiograph (DRR) generation (GPU and multicore accelerated)
 
  
−
== Usage ==
+
# superior accuracy for CT-CT (or CT-CBCT) registration
 +
# faster results for MSE registration
  
−
===Use Cases, Examples===
+
However, to date there have been no rigorous comparisons of the various 3D Slicer registration methods.
  
−
Plastimatch contains three separate plugins
+
Examples of how this module is being used:
−
 
 
−
* 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
 
* Intra-subject registration for adaptive radiotherapy
 
* Inter-subject registration for automatic segmentation

* '''Stage 0 panel:''' Stage 0 is the a pre-alignment stage, which uses either a translation, rigid transform, or affine transform to make a rough alignment of the moving image to the fixed image.  The default is not to do pre-alignment.  If your images are reasonably well aligned you can keep this option off, which makes plastimatch run faster.  But generally it doesn't hurt to enable Stage 0.

** '''Image Subsampling Rate:'''  This option is specified as three integers, separated by commas.  It tells plastimatch to subsample the images in the (x,y,z) dimensions by this amount for this stage.  This is one of the methods that plastimatch implements multi-resolution registration. by cascading stages of different subsampling rates.
−
* '''Viewing panel:'''
+
** '''Max Iterations:''' This option controls how many iterations of B-spline registration will be run in this stage.  Usually there is no benefit beyond 200 iterations.  Also, there is usually no harm in running extra iterations, except that it takes longer.
−

+
** '''Transformation:''' This option controls whether the pre-alignment uses a translation (3 DOF), a rigid transform (6 DOF), or an affine transform (12 DOF).  Generally speaking, translation is recommended unless the images are extremely different.
 +
* '''Stage 1 panel:''' Stage 1 is the first stage of non-rigid registration.  The plastimatch plugin will always do at least one non-rigid stage.

** '''Image Subsampling Rate:'''  This option is specified as three integers, separated by commas.  It tells plastimatch to subsample the images in the (x,y,z) dimensions by this amount for this stage.  This is one of the methods that plastimatch implements multi-resolution registration. by cascading stages of different subsampling rates.

** '''Grid Spacing:''' The grid spacing parameter is a floating point number which controls the size of the B-spline control grid, in mm.  Larger spacing means a smoother registration, while smaller spacing means a finer registration.
 +
* '''Stage 2 panel:''' Stage 2 is an optional second round of non-rigid registration.  If you get good results after stage 1, you might try stage 2 to further improve the results.  However, enabling stage 2 increases the time required to perform the registration.

Module Description

This is the plastimatch automatic (B-spline) deformable image registration module. It includes a multi-stage, multi-resolution pipeline, as well as multicore and GPU acceleration. Compared to other B-spline methods in 3d slicer, the plastimatch registration method might offer:

  1. superior accuracy for CT-CT (or CT-CBCT) registration
  2. faster results for MSE registration

However, to date there have been no rigorous comparisons of the various 3D Slicer registration methods.

Examples of how this module is being used:

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