Can ITK read multi-frame DCM files? For example, DSA, how to do it?

ITK can read multi-frame DICOM files. It is easier than [reading a regular DICOM series](https://examples.itk.org/src/io/gdcm/readdicomseriesandwrite3dimage/documentation). Just provide a filename which ends in `.dcm`. Any [read image](https://examples.itk.org/src/io/imagebase/readanimage/documentation) example should do.

Thanks, I use the C++ version of the code.

ImageType::Pointer image = itk::ReadImage(argv[1]);

Does image pointer point to all frame data? How can I get the frame data from the first frame to the last frame separately by this pointer?

The slices are ordered along k (usually z) coordinate. Here is an [example](https://examples.itk.org/src/filtering/imagegrid/processa2dsliceofa3dimage/documentation) which works on one slice.
