Member Function Documentation

bool ArePixelsScaled ( )

protectedvirtual

Check if the data needs to be rescaled.

References svkDcmEnhancedVolumeReader::IsDataFloatingPoint().

Referenced by svkDcmEnhancedVolumeReader::ExecuteInformation(), and svkDcmEnhancedVolumeReader::GetFileType().

int CanReadFile ( const char * fname )

virtual

Mandatory, must be overridden to get the factory to check for proper type of vtkImageReader2 to return.

References svkImageData::GetDcmHeader(), svkDcmHeader::GetStringValue(), svkDcmHeader::IsFileDICOM(), svkMriImageData::New(), and svkDcmHeader::ReadDcmFileHeaderOnly().

void ExecuteInformation ( )

protectedvirtual

Side effect of Update() method. Used to load pixel data and initialize vtkImageData Called before ExecuteData()

Reimplemented from svkDcmVolumeReader.

References svkDcmEnhancedVolumeReader::ArePixelsScaled(), and svkImageReader2::GetOutput().

int FillOutputPortInformation	(	int	port,
		vtkInformation *	info
	)

protectedvirtual

Define the output data type. This is used to initialize the output object.

Reimplemented from svkImageReader2.

virtual const char* GetDescriptiveName ( )

inlinevirtual

svkDcmHeader::DcmPixelDataFormat GetFileType ( )

protectedvirtual

Returns the pixel type. Either unsinged int or float.

Implements svkImageReader2.

References svkDcmEnhancedVolumeReader::ArePixelsScaled(), svkDcmHeader::SIGNED_FLOAT_4, svkDcmHeader::SIGNED_FLOAT_8, and svkDcmHeader::UNSIGNED_INT_2.

void GetPixelTransform	(	double &	intercept,
		double &	slope,
		svkDcmHeader *	header
	)

protected

Get the slope and intercept from the PixelValueTransformationSequence in the DICOM Header.

References svkImageReader2::GetDcmHeader(), svkImageData::GetDcmHeader(), svkImageReader2::GetOutput(), svkDcmHeader::GetStringSequenceItemElement(), and svkTypeUtils::StringToDouble().

Referenced by svkDcmEnhancedVolumeReader::IsDataFloatingPoint().

virtual svkImageReader2::ReaderType GetReaderType ( )

inlinevirtual

Implements svkImageReader2.

References svkImageReader2::DICOM_ENHANCED_MRI.

void GetRescaledPixels	(	double *	doublePixels,
		unsigned short *	shortPixels,
		double	intercept,
		double	slope,
		int	numberOfValues
	)

protected

Rescales the short data to floating point data using an intercept and slope.

void GetRescaledPixels	(	float *	floatPixels,
		unsigned short *	shortPixels,
		double	intercept,
		double	slope,
		int	numberOfValues
	)

protected

Rescales the short data to floating point data using an intercept and slope.

bool IsDataFloatingPoint ( )

protectedvirtual

Check if data is actually floating point data. The data is floating point unless the RescaleIntercept is 0 and the RescaleSlope is 1.

References svkImageReader2::GetDcmHeader(), svkImageReader2::GetOutput(), and svkDcmEnhancedVolumeReader::GetPixelTransform().

Referenced by svkDcmEnhancedVolumeReader::ArePixelsScaled().

static svkDcmEnhancedVolumeReader* New ( )

static

Referenced by svkImageReaderFactory::CreateImageReader2(), and svkImageReaderFactory::svkImageReaderFactory().

void SetRescalePixels ( bool rescalePixels )

If set to true then rescale data to floating point when appropriate.

void UseDoublePrecision ( bool useDoublePrecision )

Set to true if the data should be interpreted as double precision. This is unlikely BUT hypothetically the slope and intercept fields allow for double precision. This precision is most likely artificial.
