<p>Hi Hadi,</p>
<p>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. <br>
</p>
<p>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.</p>
<p>Best regards,</p>
<p><br>

<div dir="ltr">Dear castor users
<div>I am using castor_v2.1 and at the first I want to
calculate the coincidences with regarding the <b>maximum
axial difference</b>. Are there any way to apply this
option before reconstruction?</div>
<div>Any answer will be highly appreciated!<br>
