Get metadata from vtkNIFTIReader about vtk-dicom HOT 3 CLOSED

The vtkNIFTIHeader class is documented on this web page:
http://dgobbi.github.io/vtk-dicom/doc/api/classvtk_n_i_f_t_i_header.html

The meanings of the fields are described in the nifti documentation:
https://nifti.nimh.nih.gov/nifti-1/documentation/

For the window, use GetCalMin() and GetCalMax().
WindowCenter = (cal_min + cal_max)/2.0
WindowWidth = cal_max - cal_min
However, please note that in many nifti files, the cal_max and cal_min will be zero!

The best way to get the orientation of a nifti file is via the quaternion parameters.
The nifti documentation at the NIH website describes how to do this.
There are also some notes in the vtkNIFTIReader source code:

David, thank you for your valuable information. However, I think is about more information than that, for instance, from vtkDICOMReader I could find a lot info:

	vtkDICOMMetaData* pMeta = pDICOMReader->GetMetaData();
	pMeta->GetAttributeValue(DC::InstitutionName).AsString().c_str());
	pMeta->GetAttributeValue(DC::PatientName).AsString().c_str());
	pMeta->GetAttributeValue(DC::PatientBirthName).AsString().c_str());
	pMeta->GetAttributeValue(DC::PatientID).AsString().c_str());
	pMeta->GetAttributeValue(DC::PatientSex).AsString().c_str());

Could I have the same things from vtkNIFTIReader ? If I can, how ?

NIFTI files do not have any of that information. You might be interested in BIDS.
