Dear CASToR user´s,
I am working on a simulated PET scanner in GATE. I set up a point source in a FOV center, and set a static PET with 10 monolithic detectors. When I perform the reconstruction, the image result appears with a star artifact. How can I solve this problem? The images are attached.
Thank you for your help in advance.
Regards,
Pedro.

Hi Pedro,
Could you share some related part of your GATE macro of this simulation? I don’t think the issue is with castor, so more details will make us easier to help you.

Hi,
Have you thought about the spatial resolution capacities of a PET scanner with only 10 detectors? It might be too coarse to resolve a point source, depending on the size of the detectors etc.
