[Castor-users] Normalization

[Sadek Nehmeh]

Dear Castor Developers and Users,

I have successfully reconstructed the GATE images for a Biograph Vision. The images look great and artifact-free. The interesting thing is that even though I did not apply any normalization correction, the images do not show any rings artifacts! Could someone please clarify some details about how the sensitivity image is produced and how the algorithm compensates for the expected ring artifacts?

Thanks,
Sadek
