How does non-uniformity, or plain image noise, or SNR relate to N, number of collected counts? It depends.
For example, it is a well known fact that if one uses filtered back projection (FBP), the relation is approximately: $$SNR\propto\sqrt{N}$$ see Watson for example. However …

events per file.
I was mostly interested in how …
