<FONT FACE="Verdana">Hi Uday,<BR>
<BR>
I suggest you use the paramaterizedBoxMatrix instead. This type of voxellized phantom is available in the most recent release of GATE and better supported by GEANT. In order to use it, you need to change two things (hilighted in blue) in your script:<BR>

Hi,<BR>
<BR>
I'm trying to use a voxelized phantom in Gate and am experiencing some <BR>
problems. Following is the macro I use to define the phantom:<BR>
<BR>
/gate/world/daughters/name ncat<BR>
/gate/world/daughters/insert replicaMatrix<BR>
/gate/ncat/geometry/insertReader image<BR>
/gate/ncat/imageReader/insertTranslator range<BR>
/gate/ncat/imageReader/rangeTranslator/readTable range.dat<BR>
/gate/ncat/imageReader/rangeTranslator/describe 1<BR>
/gate/ncat/imageReader/readFile myo_atn.dat<BR>
/gate/ncat/attachPhantomSD<BR>
<BR>
I'm simulating a cylindricalPET system and all commands are accepted and <BR>
no warnings/errors are issued as Gate runs. But "gateCoincidences.dat" <BR>
remains empty. If I comment out the above macro, I get coincidences as <BR>
expected. I have added some new materials to the "GateMaterials.db" file <BR>
but they are accepted by Gate and don't seem to be a problem. Anyone who <BR>
has used a voxelized phantom successfully, please help.<BR>
<BR>
Thanks in advance,<BR>
<BR>
Uday<BR>
