Theo,
the DST parameters are listed in my code under "Define the scanner geometry parameters" section. Those are the parameters suggested by GE.

Hello there
I am trying to modify Sadeks code for the GE Discovery ST,
Does anyone know where/how I can get the
parameters,
Max Theta (??)
Number of projection planes (225)
Sinogram width (249)
for the Discovery ST ?
The values in brackets are the ones I have found out. Could someone verify
if they are correct ?
Cheers
theodore
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.
