[gate-users] Image Reconstruction of Gate output

[Nehmeh, Sadek/Medical Physics]

Hi Theodore,

If you can manage to reconstruct your Gate data with STIR it will be
easier for everybody. Otherwise we will have to work out another
permission from GE, because reconstructing on the GE console requires
giving information about the GE data format, which I don't have
permission to release.

Hello Sadek,
I just got the codes, thanks, as I told you my interest in with the DST
geometry so if you don't mind I wold like to have the other tools.
I plan to export the data ona DST station, since STIR doesn't yet
recognise DST geometry. I could work with Kris on that one but I don't
know how much of programming it will require.

Regards
Theodore
