[Paraview] Paraview Timestep information

[Moreland, Kenneth]

If you are willing to write some code, it is relatively easy to convert a reader for a single time to one that reads a file series over time.  That topic is covered on this Wiki page:

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

I am not familiar with the structure of DICOM format. Are we talking
about multiple DICOM files (i.e. a file series) or one file that has
all time steps? Also, which DICOM reader are you using and can that
reader support time?
