[ITK-users] Translation on each Dicom on a Directory

Hello,

If I understand correctly what you are saying, you were able to use
itkImageSeriesReader [1] but you do not want all your files of dimension
N-1 to be merged altogether in a file of dimension N, correct?
In this case, you will have to read each file individually with
itkImageReader. You can still use itkNumericSeriesFileNames to create the
list of file names.

Your code could look like this (modify and complete what you need:

typedef itk::NumericSeriesFileNames NameGeneratorType;
NameGeneratorType::Pointer nameGenerator = NameGeneratorType::New();
nameGenerator->SetSeriesFormat( argv[1] );

nameGenerator->SetStartIndex( first );
nameGenerator->SetEndIndex( last );
nameGenerator->SetIncrementIndex( 1 );
std::vector<std::string> names = nameGenerator->GetFileNames();

typedef itk::ImageFileReader<ImageType> ReaderType;
std::vector<std::string>::iterator nit;
for (nit = names.begin();
nit != names.end();
nit++)
{
ReaderType::Pointer reader = ReaderType::New();
reader->SetFileName((*nit).c_str());
reader->Update();
////////////
// Do your computation
////////
}

Hope this helps,
Francois

Hi,
I need to read a directory which contains X number of Dicom images. I have
no troubles doing this by passing a parameter with the name of each file to
ITK but I'd like to read one by one and do the translation in a For. Sounds
simple but I could not find an example where you read a directory, process
images one by one on a For and then write the resultant image (within the
same For) to an output directory..
Does anyone know where I can find an example (of any kind) for reading a
directory and doing some processing (any type) in a For?
Thank you!
