[Castor-users] maximum axial difference for coincidences

[tmerlin]

Hi Hadi,

This option just affects the computation of the sensitivity image for 
list-mode, in the case it is computed from the scanner geometry (not 
from a normalization datafile nor from histogram, as described in 
documentation 6.1). It is not applied during reconstruction.

What this parameter does is imposing a restriction on the axial distance 
between the detectors during the sensitivity image computation. The only 
purpose is to adapt the sensitivity image to the reconstruction of a 
dataset acquired/simulated with axial restrictions in the system geometry.

Best regards,
