[Gate-users] visualizing benchSPECT.mac

[Uwe Pietrzyk]

Hi Emma,

STIR is not restricted to PET, but allows tomographic image reconstruction in general.
In your case, you would use a module for 2D reconstruction. Please check the
STIR web-site and recommendations given there. It is open source and very actively
used in the field. However, I personally don't have an example for SPECT at hand yet.

Kind regards,

Uwe Pietrzyk
