Detailed Description

ImageIO class for reading and writing DICOM V3.0 and ACR/NEMA 1&2 uncompressed images This class is only an adaptor to the gdcm library (currently gdcm 1.2.x is used by default):

GDCM 1.2 can be found at: http://creatis-www.insa-lyon.fr/Public/Gdcm/

CREATIS INSA - Lyon 2003-2008 http://www.creatis.insa-lyon.fr

Using the CMake variable: ITK_USE_SYSTEM_GDCM it is now possible to use a system installed GDCM 2.x release. GDCM 2.x is now being developped on sourceforge.net :

http://gdcm.sourceforge.net

Documentation:

Warning:

There are several restrictions to this current writer:

Eventhough during the writing process you pass in a DICOM file as input The output file may not contains ALL DICOM field from the input file. In particular:
- The SeQuence DICOM field (SQ).
- Fields from Private Dictionary
Some very long (>0xfff) binary fields are not loaded (typically 0029|0010), you need to explicitely set the maximum length of elements to load to be bigger (see Get/SetMaxSizeLoadEntry)
GDCMImageIO was not handling rescale slope/intercept properly. This is fixed as of 11/12/2007
In DICOM some field are stored directly using there binary representation. When loaded into the MetaDataDict some fields are converted to ASCII (only VR: OB/OW/OF and UN are encoded as mime64).

Member Function Documentation

virtual void itk::LightProcessObject::AbortGenerateDataOff ( ) [virtual, inherited]

virtual void itk::LightProcessObject::AbortGenerateDataOn ( ) [virtual, inherited]

Turn on and off the AbortGenerateData flag.

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			`[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			const `[inherited]`

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

void itk::ImageIOBase::AddSupportedReadExtension ( const char * extension ) [protected, inherited]

Insert an extension to the list of supported extensions for reading.

void itk::ImageIOBase::AddSupportedWriteExtension ( const char * extension ) [protected, inherited]

Insert an extension to the list of supported extensions for writing.

static void itk::LightObject::BreakOnError ( ) [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual bool itk::GDCMImageIO::CanReadFile ( const char * ) [virtual]

Determine the file type. Returns true if this ImageIO can read the file specified.

Implements itk::ImageIOBase.

virtual bool itk::ImageIOBase::CanStreamRead ( void ) [inline, virtual, inherited]

Determine if the ImageIO can stream reading from this file. Default is false.

Reimplemented in itk::MetaImageIO, and itk::StreamingImageIOBase.

Definition at line 307 of file itkImageIOBase.h.

virtual bool itk::ImageIOBase::CanStreamWrite ( void ) [inline, virtual, inherited]

Determine if the ImageIO can stream writing to this file. Default is false.

There are two types of non exclusive streaming: pasteing subregions, and iterative If true then

Reimplemented in itk::MetaImageIO, and itk::StreamingImageIOBase.

Definition at line 331 of file itkImageIOBase.h.

virtual bool itk::GDCMImageIO::CanWriteFile ( const char * ) [virtual]

Determine the file type. Returns true if this ImageIO can write the file specified. GDCM triggers on ".dcm" and ".dicom".

Implements itk::ImageIOBase.

void itk::ImageIOBase::ComputeStrides ( ) [protected, inherited]

Calculates the different strides (distance from one thing to the next). Upon return, strides[0] = bytes to get to the next component of a pixel, strides[1] = bytes to get to the next pixel in x direction, strides[2] = bytes to get to the next row in y direction, strides[3] = bytes to get to the next slice in z direction, etc.

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const [virtual, inherited]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff ( ) const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete ( ) [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

virtual void itk::LightProcessObject::GenerateData ( void ) [inline, protected, virtual, inherited]

This method causes the filter to generate its output.

Reimplemented in itk::ClassifierBase< TDataContainer >, itk::ImageClassifierBase< TInputImage, TClassifiedImage >, itk::ImageGaussianModelEstimator< TInputImage, TMembershipFunction, TTrainingImage >, itk::ImageKmeansModelEstimator< TInputImage, TMembershipFunction >, itk::ImageModelEstimatorBase< TInputImage, TMembershipFunction >, itk::LevelSetNeighborhoodExtractor< TLevelSet >, itk::Statistics::SampleClassifier< TSample >, itk::Statistics::SampleClassifierWithMask< TSample, TMaskSample >, itk::ClassifierBase< TInputImage >, and itk::ClassifierBase< TSample >.

Definition at line 123 of file itkLightProcessObject.h.

virtual ImageIORegion itk::ImageIOBase::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requested ) const [virtual, inherited]

Method for supporting streaming. Given a requested region, determine what could be the region that we can read from the file. This is called the streamable region, which will be equal or smaller than the LargestPossibleRegion (unless it was dimensionaly clipped) and greater or equal to the RequestedRegion

the resulting IORegion may be a greater dimensions the the requested IORegion, if the the derived class is unable to read the requested region. For example if the file has a size of [ 10, 10, 10] but the requested region is [10, 10] the return may be 3 dimensions.

Reimplemented in itk::MetaImageIO, itk::NiftiImageIO, and itk::StreamingImageIOBase.

virtual const bool& itk::LightProcessObject::GetAbortGenerateData ( ) [virtual, inherited]

Get the AbortGenerateData flag for the process object. Process objects may handle premature termination of execution in different ways.

virtual unsigned int itk::ImageIOBase::GetActualNumberOfSplitsForWriting	(	unsigned int	numberOfRequestedSplits,
		const ImageIORegion &	pasteRegion,
		const ImageIORegion &	largestPossibleRegion
	)			`[virtual, inherited]`

Before this method is called all the configuration will be done, that is Streaming/PasteRegion/Compression/Filename etc If pasting is being used the number of requested splits is for that region not the largest. The derived ImageIO class should verify that the file is capable of being writen with this configuration. If pasted is enabled and is not support or does not work with the file, then an excepetion should be thrown.

The default implementation depends on CanStreamWrite. If false then 1 is returned (unless pasting is indicated), so that the whole file will be updated in one region. If true then its assumed that any arbitrary region can be writen to any file. So the users request will be respected. If a derived class has more restictive conditions then they should be checked

Reimplemented in itk::MetaImageIO, and itk::StreamingImageIOBase.

virtual unsigned int itk::ImageIOBase::GetActualNumberOfSplitsForWritingCanStreamWrite	(	unsigned int	numberOfRequestedSplits,
		const ImageIORegion &	pasteRegion
	)			const `[protected, virtual, inherited]`

an implementation of ImageRegionSplitter:GetNumberOfSplits

void itk::GDCMImageIO::GetBodyPart ( char * part )

Convenience methods to query patient information and scanner information. These methods are here for compatibility with the DICOMImageIO2 class and as such should not be used in any new code. They rely on properly preallocated buffer, which is not a good practice. Instead user are encourage to use directly the GetValueFromTag function

virtual ByteOrder itk::ImageIOBase::GetByteOrder ( ) const [virtual, inherited]

These methods indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. Note: most UNIX machines are BigEndian while PC's and VAX's are LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetByteOrderToLittleEndian() otherwise SetByteOrderToBigEndian(). Some ImageIOBase subclasses ignore these methods.

std::string itk::ImageIOBase::GetByteOrderAsString ( ByteOrder ) const [inherited]

Convenience method returns the ByteOrder as a string. This can be used for writing output files.

Command* itk::Object::GetCommand ( unsigned long tag ) [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

virtual unsigned int itk::ImageIOBase::GetComponentSize ( ) const [virtual, inherited]

Compute the size (in bytes) of the components of a pixel. For example, and RGB pixel of unsigned char would have a component size of 1 byte. This method can be invoked only after the component type is set.

Reimplemented in itk::IPLCommonImageIO.

SizeType itk::ImageIOBase::GetComponentStride ( ) const [protected, inherited]

Convenient method for accessing number of bytes to get to the next pixel component. Returns m_Strides[0].

virtual IOComponentType itk::ImageIOBase::GetComponentType ( ) const [virtual, inherited]

Set/Get the component type of the image. This is always a native type.

std::string itk::ImageIOBase::GetComponentTypeAsString ( IOComponentType ) const [inherited]

Convenience method returns the IOComponentType as a string. This can be used for writing output files.

virtual const std::type_info& itk::ImageIOBase::GetComponentTypeInfo ( ) const [virtual, inherited]

Set/Get the component type of the image. This is always a native type.

Reimplemented in itk::IPLCommonImageIO.

virtual TCompressionType itk::GDCMImageIO::GetCompressionType ( ) const [virtual]

Set/Get a boolean to use the JPEG2000 compression or not.

bool itk::Object::GetDebug ( ) const [inherited]

Get the value of the debug flag.

virtual std::vector<double> itk::ImageIOBase::GetDefaultDirection ( unsigned int i ) const [virtual, inherited]

Return the directions to be assigned by default to recipient images whose dimension is smaller than the image dimension in file.

Reimplemented in itk::AnalyzeImageIO.

virtual unsigned int itk::ImageIOBase::GetDimensions ( unsigned int i ) const [inline, virtual, inherited]

Set/Get the image dimensions in the x, y, z, etc. directions. GetDimensions() is typically used after reading the data; the SetDimensions() is used prior to writing the data.

Definition at line 109 of file itkImageIOBase.h.

virtual std::vector<double> itk::ImageIOBase::GetDirection ( unsigned int i ) const [inline, virtual, inherited]

Set/Get the image direction on an axis-by-axis basis. The SetDirection() method is required when writing the image.

Reimplemented in itk::AnalyzeImageIO.

Definition at line 135 of file itkImageIOBase.h.

virtual const char* itk::ImageIOBase::GetFileName ( ) const [virtual, inherited]

Set/Get the name of the file to be read.

virtual FileType itk::ImageIOBase::GetFileType ( ) const [virtual, inherited]

These methods control whether the file is written binary or ASCII. Many file formats (i.e., subclasses) ignore this flag.

std::string itk::ImageIOBase::GetFileTypeAsString ( FileType ) const [inherited]

Convenience method returns the FileType as a string. This can be used for writing output files.

virtual const char* itk::GDCMImageIO::GetFrameOfReferenceInstanceUID ( ) const [virtual]

Access the generated DICOM UID's.

static bool itk::Object::GetGlobalWarningDisplay ( ) [static, inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

Return the number of bytes in the image.

SizeType itk::ImageIOBase::GetImageSizeInComponents ( ) const [inherited]

Return the number of pixels times the number of components in the image.

SizeType itk::ImageIOBase::GetImageSizeInPixels ( ) const [inherited]

Return the number of pixels in the image.

void itk::GDCMImageIO::GetInstitution ( char * ins )

Convenience methods to query patient information and scanner information. These methods are here for compatibility with the DICOMImageIO2 class and as such should not be used in any new code. They rely on properly preallocated buffer, which is not a good practice. Instead user are encourage to use directly the GetValueFromTag function

virtual IOComponentType itk::GDCMImageIO::GetInternalComponentType ( ) const [virtual]

Get the original component type of the image. This differs from ComponentType which may change as a function of rescale slope and intercept.

virtual const ImageIORegion& itk::ImageIOBase::GetIORegion ( ) [virtual, inherited]

Specify the region of the image data to either read or write. The IORegion specifies the part of the image to read or write. Regions are defined with an index and a size vector. These vectors define the start (lower-left corner) and length of the region within the image. Make sure that the IORegion lies within the image.

virtual bool itk::GDCMImageIO::GetKeepOriginalUID ( ) const [virtual]

Preserve the original DICOM UID of the input files

static bool itk::GDCMImageIO::GetLabelFromTag	(	const std::string &	tag,
		std::string &	labelId
	)			`[static]`

Method for consulting the DICOM dictionary and recovering the text description of a field using its numeric tag represented as a string. If the tagkey is not found in the dictionary then this static method return false and the value "Unknown " in the labelId. If the tagkey is found then this static method returns true and the actual string descriptor of the tagkey is returned in the variable labelId.

virtual bool itk::GDCMImageIO::GetLoadPrivateTags ( ) const [virtual]

Parse any private tags in the DICOM file. Defaults to the value of LoadPrivateTagsDefault. Loading DICOM files is faster when private tags are not needed.

Warning:: this is a GDCM 1.x only option, no effect on GDCM 2.x

static bool itk::GDCMImageIO::GetLoadPrivateTagsDefault ( ) [inline, static]

Global method to define the default value for LoadPrivateTags. When instances of GDCMImageIO are created, the ivar LoadPrivateTags is initialized to the value of LoadPrivateTagsDefault. This method is useful when relying on the IO factory mechanism to load images rather than specifying a particular ImageIO object on the readers. Default is false.

Sets the reference count (use with care)

Reimplemented from itk::LightObject.

virtual void itk::ImageIOBase::SetSpacing	(	unsigned int	i,
		double	spacing
	)			`[virtual, inherited]`

Set/Get the image spacing on an axis-by-axis basis. The SetSpacing() method is required when writing the image.

virtual void itk::GDCMImageIO::SetUIDPrefix ( const char * _arg ) [virtual]

Macro to access the DICOM UID prefix. By default this is the ITK root id. This default can be overriden if the exam is for example part of an existing study.

virtual void itk::ImageIOBase::SetUseCompression ( bool _arg ) [virtual, inherited]

Set/Get a boolean to use the compression or not.

virtual void itk::ImageIOBase::SetUseStreamedReading ( bool _arg ) [virtual, inherited]

Set/Get a boolean to use streaming while reading or not.

virtual void itk::ImageIOBase::SetUseStreamedWriting ( bool _arg ) [virtual, inherited]

Set/Get a boolean to use streaming while writing or not.

virtual bool itk::ImageIOBase::SupportsDimension ( unsigned long dim ) [inline, virtual, inherited]

The different types of ImageIO's can support data of varying dimensionality. For example, some file formats are strictly 2D while others can support 2D, 3D, or even n-D. This method returns true/false as to whether the ImageIO can support the dimension indicated.

Reimplemented in itk::MetaImageIO, itk::NrrdImageIO, and itk::RawImageIO< TPixel, VImageDimension >.
