Detailed Description

Read DICOM image files.

This class reads a series of DICOM files into a vtkImageData object, and also provides access to the DICOM meta data for each file.

Member Function Documentation

GetAutoRescale()

virtual int vtkDICOMReader::GetAutoRescale ( )

virtual

Turn off automatic rescaling of stored pixel values.

By default, if the RescaleSlope and RescaleIntercept attributes are present in the DICOM data set, they will be used to rescale stored pixel values according to the DICOM modality LUT operation. The resulting values will be stored as 16-bit integers if possible, but single-precision floats will be used if the potential output range is greater than can be stored in 16 bits, or if either the RescaleSlope or the RescaleIntercept is not an integer. If AutoRescale is off, then the data is not rescaled.

GetAutoYBRToRGB()

virtual int vtkDICOMReader::GetAutoYBRToRGB ( )

virtual

Turn off automatic conversion of YBR images to RGB.

By default, YBR images are always converted to RGB (though the photometric interpretation in the metadata will remain the same).

GetFileIndexArray()

vtkIntArray* vtkDICOMReader::GetFileIndexArray ( )

inline

Get an array that converts slice index to input file index.

If the reader has generated scalar components, then this will be a two-dimensional array and calling array->GetComponent(i,j) will return the file index for slice i and scalar component j for monochrome images, or for slice i and scalar component 3*j for RGB images (or more precisely, at scalar component N*j where N is the SamplesPerPixel value from the DICOM metadata). If the data has just one component, then use j=0. If you used SetFileNames() to provide a list of files to the reader, then use this array to find out which file provided which slice, or to index into the MetaData object to get the metadata for a particular slice.

GetFrameIndexArray()

vtkIntArray* vtkDICOMReader::GetFrameIndexArray ( )

inline

Get an array that converts slice index to frame index.

The purpose of this array is to identify individual frames in multi-frame DICOM files. The dimensions of this array are identical to the FileIndexArray. Use FileIndexArray to identify the file, then use FrameIndexArray to identify the frame within that file.

GetMetaData()

vtkDICOMMetaData* vtkDICOMReader::GetMetaData ( )

inline

Get the meta data for the DICOM files.

The Get() method of vtkDICOMMataData takes optional file and frame indices, which specify the file and the frame within that file to get the attribute from. If you have a slice index rather than a file index and frame index, then use the FileIndexArray and FrameIndexArray to convert the slice index into file and frame indices.

GetOverlayOutput()

vtkImageData* vtkDICOMReader::GetOverlayOutput

(

)

Get the overlay.

The extent of the overlay will be the same as the main image. For multiple overlays, each overlay will be stored in a different bit. An 8-bit image will be used if there are eight or fewer overlays, and an unsigned 16-bit image will be used if there are more than eight overlays.

GetPatientMatrix()

vtkMatrix4x4* vtkDICOMReader::GetPatientMatrix ( )

inline

Get a matrix to place the image within DICOM patient coords.

This matrix is constructed from the ImageOrientationPatient and ImagePositionPatient meta data attributes. See the SetMemoryRowOrder method for additional information.

GetRescaleSlope()

double vtkDICOMReader::GetRescaleSlope ( )

inline

Get the slope and intercept for rescaling the scalar values.

If AutoRescale in On (which is the default), then GetRescaleSlope() will return 1 and GetRescaleIntercept() will return zero. Otherwise, they will return the RescaleSlope and RescaleIntercept for the data set. Use the equation v = u*RescaleSlope + RescaleIntercept.

Note that the returned values might not be valid if these attributes are not the same for all slices in the series. Use the meta data to retrieve the per-slice slope and intercept.

GetStackIDs()

vtkStringArray* vtkDICOMReader::GetStackIDs ( )

inline

Get a list of the stacks that are present in the input files.

A stack is a contiguous array of slices that form a volume.

GetTimeAsVector()

virtual int vtkDICOMReader::GetTimeAsVector ( )

virtual

Read the time dimension as scalar components (default: Off).

If this is on, then each time point will be stored as a scalar component in the image data. If the data has both a time dimension and a vector dimension, then the number of components will be the product of these two dimensions, i.e. the components will store a sequence of vectors, one vector for each time point.

IsA()

virtual vtkTypeBool vtkDICOMReader::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageReader2.

RegisterCodecs()

static void vtkDICOMReader::RegisterCodecs ( )

static

Control registration of image codecs (DCMTK-specific).

If the reader has been compiled with DCMTK support, RegisterCodecs() allows manual registration of the DCMTK codecs by the application. If you do not call this method, the reader will automatically register the codecs when it is instantiated. The registration is internally guarded by a refererence count, and every RegisterCodecs() call must eventually be matched by an UnRegisterCodecs() call.

SetDefaultCharacterSet()

void vtkDICOMReader::SetDefaultCharacterSet

(

vtkDICOMCharacterSet

cs

)

Set the character set to use if SpecificCharacterSet is missing.

Some DICOM files do not list a SpecificCharacterSet attribute, but nevertheless use a non-ASCII character encoding. This method can be used to specify the character set in absence of SpecificCharacterSet. This method will not take effect unless is is called before the image is read. If SpecificCharacterSet is present, the default will not override it unless OverrideCharacterSet is true.

SetDesiredStackID()

void vtkDICOMReader::SetDesiredStackID

(

const char *

stackId

)

Set the Stack ID of the stack to load, for named stacks.

If the series has multiple stacks, then by default the reader will only load the first stack. This method allows you to select a different stack, if you know the DICOM StackID for the stack.

SetMemoryRowOrder()

void vtkDICOMReader::SetMemoryRowOrder

(

int

order

)

Set the ordering of the image rows in memory.

If the order is BottomUp (which is the default) then the images will be flipped when they are read from disk. The native orientation of DICOM images is top-to-bottom.

SetOutputScalarType()

virtual void vtkDICOMReader::SetOutputScalarType ( int  )

virtual

Set the scalar type of the output.

The default value is -1, which means that the input scalar type will be used to set the output scalar type (accounting for any type changes required by AutoRescale). Allowed output scalar types are VTK_SIGNED_CHAR, VTK_UNSIGNED_CHAR, VTK_SHORT, VTK_UNSIGNED_SHORT, VTK_INT, VTK_UNSIGNED_INT, VTK_FLOAT, or VTK_DOUBLE. The output data values will be clamped to the limits of the output type.

SetOverrideCharacterSet()

virtual void vtkDICOMReader::SetOverrideCharacterSet ( bool  )

virtual

Override the value stored in SpecificCharacterSet.

This method can be used if the SpecificCharacterSet attribute of a file is incorrect. It overrides the SpecificCharacterSet with the DefaultCharacterSet.

SetSorter()

void vtkDICOMReader::SetSorter

(

vtkDICOMSliceSorter *

sorter

)

Set a custom sorter to be used to sort files and frames into slices.

The default sorter uses the attributes "ImagePositionPatient" and "ImageOrientationPatient" to spatially arrange the slices.

ValidateStructure()

virtual bool vtkDICOMReader::ValidateStructure ( vtkIntArray *  fileArray, vtkIntArray *  frameArray  )

protectedvirtual

Verify that the files can be composed into a volume.

This is called after SortFiles has been called. It should invoke an error event and return zero upon failure.

Member Data Documentation

NumberOfPackedComponents

int vtkDICOMReader::NumberOfPackedComponents

protected

The number of packed pixel components in the input file.

This is for packed, rather than planar, components.
