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), including support for image masking, landmark penalties, and regularization * Demons method for deformable image registration (GPU accelerated) * Multi-atlas segmentation * ITK-based algorithms for translation, rigid, affine, multiple demons methods, 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 * Extensive toolchain for radiotherapy research, including support for DICOM, DICOM-RT, DICOM SRO, XiO file format, gamma analysis, contour manipulation, contour overlap analysis, and vector field analysis 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)
