CBeam_geometry
CBspline_header	Encapsulates the B-spline grid geometry
CBspline_xform	Encapsulates the B-spline coefficients used by native registration and warping algorithms. Information describing the B-spline geometry is held in the base class: Bspline_header
CDcmtk_file

CDcmtk_series	The Dcmtk_series object encapsulates a set of Dcmtk_file objects which belong to a single series
CDcmtk_slice_data
CDcmtk_sro
CDice_statistics	Computes a Dice statistic for the overlap between two regions. Dice is defined as
CDicom_sro_save	The Dicom_sro_save is a utility class for saving DICOM Spatial Registration objects from different input sources. The input images may either already exist as DICOM, in which case the SRO will reference the existing series, or they may be written by this class

CGamma_dose_comparison	Executes a comparison between two dose distributions based on the "gamma index" defined by Dan Low et al. in the following reference: Low et al, A technique for the quantitative evaluation of dose distributions, Med Phys. 1998 May;25(5):656-61. The comparison is based on searching a local neighborhood for the most similar dose. The similarity is computed as the geometric mean of the dose difference and spatial distance. The gamma value at a point is then the minimum of this similarity value over the the neighborhood. Generally, the gamma value is normalized based on a spatial tolerance and a dose difference tolerance such that gamma values of less than 1.0 are acceptable, and gamma values greater than 1.0 are unacceptable
CGeometry_chooser	Convenient method for choosing the right output geometry for a function
CHausdorff_distance	The Hausdorff class computes the worst-case distance between two regions. There are many variants of the Hausdorff. See for example:
Chnd_header
CImage_boundary	Takes an input image (binary) and computes an output image. Voxels of the output image will be one if they are (1) non-zero in the input image, and (2) have a zero voxel in their six-neighborhood. Other output image voxels will have value zero
CImage_center	Computes the center of mass of a binary image
CImage_stats
CItk_volume_header
CJacobian
CJacobian_stats
CLabeled_point
CMetadata	Encapsulate DICOM metadata for a single series. It is implemented as a map from string to string, where the key string is of the form "XXXX,XXXX"
COption_range
CParameter_parser	Abstract base class which is used to parse ini-style file formats that control the registration, mabs, and dose calculation codes
CPlm_exception
CPlm_image	Three-dimensional volume. The volume is an abstraction that can contain a volume in either native format (Volume), or ITK format (itk::Image), in any type (unsigned char, float, etc.), or in several commonly used extensions ()
CPlm_image_header	Defines the geometry of an image. It defines image origin, spacing, dimensions, and direction cosines, but does not contain image voxels
CPlm_image_private
CPlm_image_set	Set of three-dimensional volumes. It is used for importing DICOM or XiO volumes which are scanned at multiple slice spacings

The Rt_study_metadata includes separate metadata for image, dose, and rtstruct, as well as a study_metadata which is shared by all components. Items such as Patient Name or Study Description will be held in study_metadata
