[Gate-users] Spatial Resolution

[Milad Fard]

Hi dear Gaters

I am working on a cylindricalPET and I want to evaluate the spatial
resolution.
In accordance with the NEMA NU-4 2008 standards,
I simulated a spherical 22Na point source to measure the spatial resolution.

I have some issues about reconstruction the image.
I installed STIR, but I don't know how can I use my root or ASCII
coincidences file on STIR?
I installed also the package GATE_PET_2_STIR but the root file is not
recognized.

Do you have alternatives?
Does anyone know how to do it or has any clue?

Best regards,
