hey,
I have pasted an code excerpt from mitk::dicomseriedreader documentation
"usage" and have a doubt regarding the underlying concept.
DicomSeriesReader::FileNamesGrouping allImageBlocks =
DicomSeriesReader::GetSeries("/home/who/dicom/");
DicomSeriesReader::StringContainer seriesToLoad = allImageBlocks[...]; //
decide what to load
DicomSeriesReader::StringContainer oneBlockSorted =
DicomSeriesReader::SortSeriesSlices(seriesToLoad);
DataNode::Pointer node = DicomSeriesReader::LoadDicomSeries(
oneBlockSorted );
Image::Pointer image = dynamic_cast<mitk::Image*>( node->GetData() );
can anyone explain the 2nd line in the code.? what does it mean
allImageBlocks[...] ?
also when the datanode::pointer node loads the sorted block..doesnt it mean
that it contains all the slices ? if yes,then how can i use all the slices
from that "oneBlockSorted".
I am doubtful because the last line accesses the data in the node with
GetData.
shouldnt it be a loop.. something like
while (! node.size) {
Image::Pointer image = dynamic_cast<mitk::Image*>( node->GetData() );
....
...
... // proceesing using the "image"
}
thanks
