first vtkDICOMImageReader doesn't support getting DICOM image properties for<br clear="none">
now(tested in vtk v7).<br clear="none">
To read DICOM image properties you need to download GDCM can be downloaded<br clear="none">
from here <<a rel="nofollow" shape="rect" target="_blank" href="https://sourceforge.net/projects/gdcm/">https://sourceforge.net/ projects/gdcm/</a>><br clear="none">
<br clear="none">
after download and extracting GDCM you need to open CMake<br clear="none">
in CMake Check those attributes<br clear="none">
1-GDCM_USE_VTK and select VTK_DIR and vtk directory<br clear="none">
2-GDCM_BUILD_SHARED_LIBS<br clear="none">
3-GDCM_BUILD_APPLICATIONS<br clear="none">
now click configure and generate. Use your compiler to build it.<br clear="none">
<br clear="none">
In my case I got error while building GDCM that it could not find vtk lib<br clear="none">
files. which I already had in the folder. So I had to edit<br clear="none">
gdcm-2.6.6/build/cmake_ install.cmake file under INSTALL DESTINATION I had to<br clear="none">
add lib in front of vtkCommonCore-7.0.dll and the rest of the files, since<br clear="none">
in my vtk bin folder all my files had lib prefix.<br clear="none">
<br clear="none">
once GDCM is ready now you need to configure vtk<br clear="none">
open vtk in CMake and set and check those attributes<br clear="none">
1-GDCM_DIR select the build directory of GDCM<br clear="none">
2-USE_GDCM<br clear="none">
now configure and generate.<br clear="none">
now you are ready to build vtk.<br clear="none">
<br clear="none">
next thing you need to do is set environment variable for gdcm and import<br clear="none">
lib to your project.<br clear="none">
now you are ready to use GDCM<br clear="none">
<br clear="none">
To get DICOM image properties you need to do the following<br clear="none">
<br clear="none">
vtkSmartPointer< vtkGDCMImageReader> reader =<br clear="none">
vtkSmartPointer< vtkGDCMImageReader>::New();<br clear="none">
reader->SetFileName(filename. c_str());<br clear="none">
reader->Update();<br clear="none">
reader-> GetMedicalImageProperties()-> GetPatientName(); // to get Patient<br clear="none">
Name as an example<br clear="none">
<br clear="none">
double w,l;<br clear="none">
reader-> GetMedicalImageProperties()-> GetNthWindowLevelPreset(0, &w, &l); //<br clear="none">
get window width and window level.<br clear="none">
<br clear="none">
Hope this helps.<br clear="none">
