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://www.creatis.insa-lyon.fr/software/public/Gdcm/

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

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 developed on sourceforge.net :

    http://gdcm.sourceforge.net

Documentation:

• http://sourceforge.net/apps/mediawiki/gdcm/index.php?title=ITK_USE_SYSTEM_GDCM
• http://sourceforge.net/apps/mediawiki/gdcm/index.php?title=GDCM_Release_2.0

Warning

There are several restrictions to this current writer:

• Even though 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).

Wiki Examples:

• All Examples

• Resample a DICOM series

Member Function Documentation

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::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.

virtual::itk::LightObject::Pointer itk::GDCMImageIO::CreateAnother ( void  ) const

virtual

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::LightProcessObject.

void itk::GDCMImageIO::GetBodyPart

(

char *

part

)

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

virtual

Set/Get a compression type to use.

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

virtual

Access the generated DICOM UID's.

void itk::GDCMImageIO::GetInstitution

(

char *

ins

)

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 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 and load any private tags in the DICOM file. Loading DICOM files is faster when private tags are not needed. Default is false.

static bool itk::GDCMImageIO::GetLoadPrivateTagsDefault ( )

inlinestatic

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.

Warning

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

Definition at line 267 of file itkGDCMImageIO.h.

virtual bool itk::GDCMImageIO::GetLoadSequences ( ) const

inlinevirtual

Parse any sequences in the DICOM file. Defaults to the value of LoadSequencesDefault. Loading DICOM files is faster when sequences are not needed.

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.

virtual void itk::GDCMImageIO::SetLoadSequences ( const bool  )

inlinevirtual

Parse any sequences in the DICOM file. Defaults to the value of LoadSequencesDefault. Loading DICOM files is faster when sequences are not needed.

Warning

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

static void itk::GDCMImageIO::SetLoadSequencesDefault ( bool  )

inlinestatic

Global method to define the default value for LoadSequences. When instances of GDCMImageIO are created, the ivar LoadSequences is initialized to the value of LoadSequencesDefault. 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.

Warning

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

virtual void itk::GDCMImageIO::SetMaxSizeLoadEntry ( const long  )

inlinevirtual

A DICOM file can contains multiple binary stream that can be very long For example an Overlay on the image. Most of the time user do not want to load this binary structure in memory since it can consume lot of memory. Therefore any field that is bigger than the default value 0xfff is discarded and just seek'd This method allow advanced user to force the reading of such field

Warning

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

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::GDCMImageIO::Write ( const void *  buffer )

virtual

Writes the data to disk from the memory buffer provided. Make sure that the IORegion has been set properly.

Implements itk::ImageIOBase.

virtual void itk::GDCMImageIO::WriteImageInformation ( )

virtual

Writes the spacing and dimensions of the image. Assumes SetFileName has been called with a valid file name.

Implements itk::ImageIOBase.
