<p class=MsoNormal>Dear Gaters.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I would like to limit coincidences between rings of
detectors in PET. I use PETscanner system. It has within a ring several
detectors, and 3 rings of detectors. I took minimumSectorDifference as 3. All
is ok, but now I would like to limit the coincidences – and throw out all
that happen between first and third ring, leaving these within same ring and
these between ring 1 and 2 and these between ring 2 and 3. Any idea how to do
it within macros of Gate? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can manipulating with levels and command <span
style='font-family:Courier'>/gate/digitizer/Coincidences/setDepth number
(explained in section 8.4.2) can do the job, with some tricky block building?</span><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I would like to avoid sorting out events in root file after
the simulation, as this is artificial for digitizer module. If this is impossible
within macros – maybe somebody has modified Gate source code to do it and
has some extra command created?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I use Gate 3.0.0, but if needed, would switch to v.5.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Best regards<o:p></o:p></p>
