void AddRestriction (TagKey const &key)
void AddRestriction (TagKey const &key, std::string const &value, int op)
 add a rule for restricting a DICOM file to be in the serie we are trying to find. For example you can select only the DICOM files from a directory which would have a particular EchoTime==4.0. This method is a user level, value is not required to be formatted as a DICOM string
void AddRestriction (uint16_t group, uint16_t elem, std::string const &value, int op)
 add a rule for restricting a DICOM file to be in the serie we are trying to find. For example you can select only the DICOM files from a directory which would have a particular EchoTime==4.0. This method is a user level, value is not required to be formatted as a DICOM string
void SetUseSeriesDetails (bool useSeriesDetails)
 Use additional series information such as ProtocolName and SeriesName to identify when a single SeriesUID contains multiple 3D volumes - as can occur with perfusion and DTI imaging.
bool GetUseSeriesDetails ()
void CreateDefaultUniqueSeriesIdentifier ()
 This function will add the following DICOM tag as being part of a 'fake' uid. This is usefull when the Serie UID is not enough to disseminate into multiple sub serie when needed: 0020 0011 Series Number 0018 0024 Sequence Name 0018 0050 Slice Thickness 0028 0010 Rows 0028 0011 Columns.

std::string CreateUserDefinedFileIdentifier (File *inFile)
 Allow user to build is own File Identifier (to be able to sort temporal series just as he wants) Criterions will be set with AddSeriesDetail. (Maybe the method should be moved elsewhere -File class? FileHelper class?-.

Member Function Documentation

bool GDCM_NAME_SPACE::SerieHelper::AddFile (  File *  header  ) 
 

add a GDCM_NAME_SPACE::File to the first (and supposed to be unique) file set of the GDCM_NAME_SPACE::SerieHelper.

Warning:
: this method should be used by aware users only! Passing a GDCM_NAME_SPACE::File* has the same effect than passing a file name!
Todo:
: decide which one is wrong (the method, or the commentary)! the following comment doesn't match the method :-( User is supposed to know the files he want to deal with and consider them they belong to the same Serie (even if their Serie UID is different) user will probabely OrderFileList() this list (actually, ordering user choosen gdm::File is the sole interest of this method) Moreover, using vtkGdcmReader::SetCoherentFileList() will avoid vtkGdcmReader parsing twice the same files. *no* coherence check is performed, but those specified by SerieHelper::AddRestriction()
Parameters:
header GDCM_NAME_SPACE::File* of the file to deal with
Returns:
true if file was added, false if file was rejected

std::string GDCM_NAME_SPACE::SerieHelper::CreateUniqueSeriesIdentifier (  File *  inFile  ) 
 

Heuristics to *try* to build a Serie Identifier that would ensure all the images are coherent.

By default, uses the SeriesUID. If UseSeriesDetails(true) has been called, then additional identifying information is used. We allow user to add his own critierions, using AddSeriesDetail (he knows more than we do about his images!) ex : in tagging series, the only pertnent tag is 0018|1312 [In-plane Phase Encoding Direction] value : ROW/COLUMN

Parameters:
inFile GDCM_NAME_SPACE::File we want to build a Serie Identifier for.
Returns:
the SeriesIdentifier
