Detailed Description

Class for building 3D fields from slice image data.

Definition at line 77 of file cmtkVolumeFromSlices.h.

Constructor & Destructor Documentation

cmtk::VolumeFromSlices::VolumeFromSlices ( ) [inline]

Default constructor.

Definition at line 81 of file cmtkVolumeFromSlices.h.

virtual cmtk::VolumeFromSlices::~VolumeFromSlices ( ) [inline, virtual]

Virtual dummy destructor.

Definition at line 84 of file cmtkVolumeFromSlices.h.

Member Function Documentation

UniformVolume::SmartPtr cmtk::VolumeFromSlices::FinishVolume ( ) [inline, protected]

Finish volume creation without additional information.

If the additional information returned by the previous FinishVolume(...) function is not reuqired, this function may be called instead.

Definition at line 124 of file cmtkVolumeFromSlices.h.

virtual void cmtk::VolumeFromSlices::HandleError ( const char * message ) const [inline, protected, virtual]

Handle an error condition.

Basically, this function is intended to notify the user of errors occurring during the volume building process, such as inconsistent images. By default, all errors are simply printed to the standard error output. Derived classes may override this function to provide environment-specific interaction.

Parameters:

message A textual description of the error condition.

Member Data Documentation

int cmtk::VolumeFromSlices::BlockSize [private]

Number of continuous bytes that can be copied.

Definition at line 236 of file cmtkVolumeFromSlices.h.

int cmtk::VolumeFromSlices::BytesPerPixel [private]

Number of allocated bytes per voxel.

Definition at line 209 of file cmtkVolumeFromSlices.h.

unsigned int cmtk::VolumeFromSlices::DataSize [private]

Number of voxels.

Definition at line 200 of file cmtkVolumeFromSlices.h.

ScalarDataType cmtk::VolumeFromSlices::DataType [private]

Primitive image data type.

Definition at line 215 of file cmtkVolumeFromSlices.h.

DataGrid::IndexType cmtk::VolumeFromSlices::Dims [private]

Dimensions of the 3D data.

This array is filled with the number of voxels in x-, y-, and z-direction.

Definition at line 185 of file cmtkVolumeFromSlices.h.

ScalarImage::SpaceVectorType cmtk::VolumeFromSlices::FirstImagePosition [private]

X-coordinate of image origin.

Definition at line 221 of file cmtkVolumeFromSlices.h.

ScalarImage::SpaceVectorType cmtk::VolumeFromSlices::ImageOrientation[2] [private]

X-coordinate of image origin.

Definition at line 227 of file cmtkVolumeFromSlices.h.

ScalarImage::SpaceVectorType cmtk::VolumeFromSlices::ImagePosition [private]

X-coordinate of image origin.

Definition at line 224 of file cmtkVolumeFromSlices.h.

ScalarImage::SpaceVectorType cmtk::VolumeFromSlices::IncrementVector [private]

Vector between the origins of subsequent images.

Once two images have been read, the difference of their origins in 3D space is copied to this field. The origins of subsequent slices must then be in the very same direction in order to make up a rectangular 3D volume.

int cmtk::VolumeFromSlices::IncX [private]

Coordinate increment in x-direction for every block copy operation.

Definition at line 230 of file cmtkVolumeFromSlices.h.

int cmtk::VolumeFromSlices::IncY [private]

Coordinate increment in y-direction for every block copy operation.
