Detailed Description

Read series of image files into a SimpleITK image.

For some image formats such as DICOM, images also contain associated meta-data (e.g. imaging modality, patient name etc.). By default the reader does not load this information (saves time). To load the meta-data you will need to explicitly configure the reader, MetaDataDictionaryArrayUpdateOn, and possibly specify that you also want to load the private meta-data LoadPrivateTagsOn.

Once the image series is read the meta-data is directly accessible from the reader.

Note: If the pixel type for the returned image is not specified it is deduced from the first image in the series. This approach is computationally efficient and assumes that all images in a series have the same pixel type. In rare situations this is not the case, not all images have the same pixel type. If this leads to a narrowing conversion (e.g. first image pixel type is unsigned int and others are float) the returned image does not represent the data correctly. To resolve such situations, explicitly specify the expected pixel type via the SetOutputPixelType method before reading the series.

◆ Execute()

Image itk::simple::ImageSeriesReader::Execute ( )

overridevirtual

Set/Get The output PixelType of the image.

By default the value is sitkUnknown, which enable the output pixel type to be same as the file. If the pixel type is specified then the itk::ConvertPixelBuffer will be used to convert the pixels.

Implements itk::simple::ImageReaderBase.

◆ GetGDCMSeriesFileNames()

static std::vector<std::string> itk::simple::ImageSeriesReader::GetGDCMSeriesFileNames	(	const std::string &	directory,
		const std::string &	seriesID = `""`,
		bool	useSeriesDetails = `false`,
		bool	recursive = `false`,
		bool	loadSequences = `false`
	)

static

Generate a sequence of filenames from a directory with a DICOM data set and a series ID.

This method generates a sequence of filenames whose filenames point to DICOM files. The data set may contain multiple series. The seriesID string is used to select a specific series. The ordering of the filenames is based on one of several strategies, which will read all images in the directory ( assuming there is only one study/series ).

Parameters

directory	Set the directory that contains the DICOM data set.
recursive	Recursively parse the input directory.
seriesID	Set the name that identifies a particular series. Default value is an empty string which will return the file names associated with the first series found in the directory. If the parameter value was obtained from a call to GDCMSeriesIDs, the value of the useSeriesDetails parameter must be the same here and in the call to GDCMSeriesIDs.
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.
loadSequences	Parse any sequences in the DICOM data set. Loading DICOM files is faster when sequences are not needed.

◆ GetGDCMSeriesIDs()

static std::vector<std::string> itk::simple::ImageSeriesReader::GetGDCMSeriesIDs	(	const std::string &	directory,
		bool	useSeriesDetails = `false`
	)

static

Get all the seriesIDs from a DICOM data set.

Parameters

directory	The directory that contains the DICOM data set
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. The parameter value must match the value used in the call to GDCMSeriesFileNames.

◆ GetMetaData()

std::string itk::simple::ImageSeriesReader::GetMetaData	(	unsigned int	slice,
		const std::string &	key
	)		const

inline

Get the value of a meta-data dictionary entry as a string.

If the key is not in the dictionary then an exception is thrown.

string types in the dictionary are returned as their native string. Other types are printed to string before returning.

◆ GetMetaDataDictionaryArrayUpdate()

bool itk::simple::ImageSeriesReader::GetMetaDataDictionaryArrayUpdate ( )

inline

Definition at line 79 of file sitkImageSeriesReader.h.

◆ GetMetaDataKeys()

std::vector<std::string> itk::simple::ImageSeriesReader::GetMetaDataKeys ( unsigned int slice ) const

inline

Get the meta-data dictionary keys for a slice.

This is only valid after successful execution of this filter and when MetaDataDictionaryArrayUpdate is true. Each element in the array corresponds to a "slice" or filename read during execution.

If the slice index is out of range, an exception will be thrown.

Returns a vector of keys to the key/value entries in the file's meta-data dictionary. Iterate through with these keys to get the values.

Set/Get whether the meta-data dictionaries for the slices should be read. Default value is false, because of the additional computation time.
