[Rtk-users] error on build rtk in visual studio 2012 when rtk use cuda

[safdary mohsen]

Hi

I cheched projectionreader and i abtained that all projection are readed.
( by using:

typedef itk::ImageFileWriter<OutputImageType> WriterType;

WriterType::Pointer writer = WriterType::New();

writer->SetFileName( "reader.mha" );

writer->SetInput( reader->GetOutput() );

writer->Update();
)

and

geometry is work for cpu mode means outputs are ok .


I am confused for solving this problem!!!!!!!!!!!!!!!!!
