[Paraview] Paraview Timestep information

[Biao She]

We are talking about multiple DICOM files (a file series).
Each DICOM file has its own DICOM tags. These tags contain the information
of the specific DICOM file. Different DICOM file may have the same tag
values (i.e. patient ID, Acquisition Time).
In my case, for simplicity, suppose all my DIOCM files have the same patient
ID, but they don't have the same Acquisition Time. There are 10 different
acquistion times in total. So, my DICOM files can divide to 10 groups and
each group of DICOM files have the same acquisition time. Also, each group
represents the same object (because they have the same patient ID).
The reader I want will enable Paraview to aware of this acquisition time
information in DICOM files and animate the DICOM files according to the
information (from group 0 to group 9).
Currently, I use the vtkDICOMImageReader to read one group of DICOM files.
This reader doesn't support reading acquisition time information. But
reading acquisition time shouldn't be very hard to implement. The things
that I am not sure is that how to relate the time information to this group
of DIOCM files (i.e. group 0), and then keep reading until all the groups
are being read?
I hope I explain my question clear using my broken english, please let me
know if not.
Thanks
