[gate-users] Image Reconstruction of Gate output

Wed Dec 15 21:56:47 CET 2004

Theodore, for the STIR reconstruction you should have everything you
need in that attachment I sent earlier today. In the beginning of the
code I define the parameters of the DLS, and I have all the DST
parameters mentioned their as well. Change the DLS parameters to DST,
and then just follow the instrcutions in the README.txt file I have in
my attachment. If you get any problems/questions please let me know. OH,
you should run version 1.3 of STIR which has the DST geometry as Kris
mentioned. Good luck.

Hello Sadek,
Well as you say it  will be easier for everyone  if I use STIR. It's ok
by me, I was hoping to import the data and use the GE stuff. But if you
send me the other tools I need to use STIR for the DST geometry it will
be fine.
Or I can ask our guys at Uppsala IMANET to work out a permission from GE
for you to release the information.

Thanks
Theo
