<div><br class="">
</div>
<div>If not, then Gate cannot find and access the LUTs. Check the directories.</div>
<div>If yes, good sign! Maybe then you should try defining both, the surface outside-crystal & crystal outside. Just to make sure you defined the correct one. </div>

<div>If you still have problems please share more details.</div>

Dear all<br class="">
how we could create hounsfiled text file for series of DICOM files ?<br class="">

Dear all,<br class="">
<br class="">
I'm quite new to use Davis LUT model for optical simulation, so I just<br class="">
simply tested the example file in vGATE 8.2<br class="">
(/gate/GateContrib/imaging/LUTDavisModel) with setting the output format as<br class="">
ascii.<br class="">
<br class="">
When I changed the optical boundary surface setting between the crystal and<br class="">
the outside such as Rough, RoughESR_LUT, nothing changes in the light<br class="">
output (e.g., # of optical transportation to the pixel) for 511 keV gamma<br class="">
rays. According to several references, or also in common sense, light<br class="">
output should be larger with any kind of reflector attached.<br class="">
I attached my output (511 keV peak histogram) below.<br class="">
<br class="">
I checked that I enabled the GATE_USE_OPTICAL and GATE_USE_DAVIS, and I<br class="">
think the G4RealSurface2.1.1 was correctly installed.<br class="">
<br class="">
Please tell me if there is something I missed.<br class="">
<br class="">
Thank you for any help.<br class="">
<br class="">
Sincerely,<br class="">
Seungeun<br class="">
