示例1: retrieveITKImage
//read CT image
void CTImageTreeItem::retrieveITKImage(QProgressDialog *progress, int progressScale, int progressBase) {
//define and create file reader
typedef ReaderProgress::ReaderType ReaderType;
ReaderType::Pointer imageReader = ReaderType::New();
ReaderType::FileNamesContainer fc;
//assign filenames
fc.assign(m_fnList.begin(), m_fnList.end());
//set ImageIO and filenames
itk::GDCMImageIO::Pointer gdcmImageIO = itk::GDCMImageIO::New();
imageReader->SetImageIO( gdcmImageIO );
imageReader->SetFileNames(fc);
//create reader progress
ReaderProgress::Pointer progressor = ReaderProgress::New();
if (progress)
{
progressor->setDialog( progress, progressScale, progressBase );
imageReader->AddObserver(itk::AnyEvent(), progressor);
}
//try to read the images
try {
imageReader->Update();
}catch( itk::ExceptionObject & excep ) {
std::cerr << "Exception caught !" << std::endl;
std::cerr << excep << std::endl;
}
//assign the reader output to an image pointer
ImageType::Pointer imagePtr = imageReader->GetOutput();
setITKImage(imagePtr, 1);
//emit signal, that data has changed
m_model->dataChanged(m_model->createIndex(childNumber(),0,parent()),m_model->createIndex(childNumber(),columnCount()-1,parent()));
