Detailed Description

Class that defines how to read Bruker file format.

The following is a brief description of the Bruker file format.

Within the directory representing a 'session' on the scanner, data is laid out thus:

session/ 1/ <- Series/Acquisition number method <- An important header file acqp <- Another important header fid <- Raw data other unimportant files pdata/ 1/ <- Reconstruction number (may be multiple) 2dseq <- Reconstructed data visu_pars <- Most important header reco <- Mostly duplicated in visu_pars procs <- Unimportant header id <- Unimportant header 2/ ...

The minimum required data to read the image is the '2dseq' and 'visu_pars' file. To use this reader, specify the 2dseq file as the filename. It will check for the existence of the visu_pars file. If both these exist, the file is opened. If the other header files exist (method, acqp, etc.) in the correct locations then they will be read and added to the meta-data dictionary, but they are not used to read the image data itself.

This class supports reading only.

This file reader has been updated for ParaVision 6 2dseq files. The original code was written by Don C. Bigler at Penn State in 2004. It has been significantly changed, as Bruker also changed the format for ParaVision 6. In particular a new header file, 'visu_pars' was introduced that means that multiple headers no longer need to be read in order to read the '2dseq' file. However, if the other Bruker headers are still present they are read and added to the meta-data in case users wish to extract data from them.

The original implementation was contributed as a paper to the Insight Journal https://hdl.handle.net/1926/1381

bool itk::Bruker2dseqImageIO::CanReadFile ( const char * FileNameToRead )

overridevirtual

Determine if the necessary files exist to read the specified 2dseq file. Returns true if all required files exist.

Implements itk::ImageIOBase.

bool itk::Bruker2dseqImageIO::CanWriteFile ( const char * )

inlineoverridevirtual

Writing files has not been implemented for Bruker 2dseq. This function will always return false.

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::Bruker2dseqImageIO::CreateAnother ( ) 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.

virtual const char* itk::Bruker2dseqImageIO::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

static Pointer itk::Bruker2dseqImageIO::New ( )

static

New macro for creation of through a SmartPointer.

void itk::Bruker2dseqImageIO::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const

overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::ImageIOBase.

void itk::Bruker2dseqImageIO::Read ( void * buffer )

overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

void itk::Bruker2dseqImageIO::ReadImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.
