Creating a time series DICOM file is quite complicated.

If you really want to do this, start with DCMTK, witch is the better DICOM lib 
ever made, it's free and now the code is documented for "Doxygen"

http://dicom.offis.de/

what you need in the dicom "header", is the "time-vector" :
(0054,0070) US 
1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1\1... # 544,272 
TimeSlotVector  

and if you work with the projections, you also need the "angular-vector" :
(0054,0090) US 
1\2\3\4\5\6\7\8\9\10\11\12\13\14\15\16\17\18\19\20\21\22\23\24\25... # 544,272 
AngularViewVector

and ... also all the dicom basic stuff ...

so you need to be quite skilled in C++ and DICOM 3 file format.

good luck !

Hi All,

I have a series of DICOM images (3D, sequential slices) that create a time
series, derived from the NCAT phantom.  I am however having difficulty in
combining all these individual files to create the time series animation.  I
am a newby and would like to get involved with gate but would like to master
using the NCAT phantom first.

Has anyone suggestions on how to view this time series, preferably in an
open source enviroment (Amide, image J).  I would also preferably like to
combine this data into one DICOM file to port into a Philips system for
further analysis

Thanks alot for any help.
