[Gate-users] RE: blurring

[anayisse arnaud]

Hi Marcin,
 
I need your help please.
 
to answer your question, All my benchmarks use the global blurring and not the intrinsic blurring ? why this question please ?
 
And As I explained to you : When I use the quantum efficiency I can't run the macro ??? 
# DEFINE QUANTUM EFFICIENCY OF THE PHOTODETECTOR
/gate/digitizer/Singles/insert quantumEfficiency
/gate/digitizer/Singles/quantumEfficiency/chooseQEVolume crystal
/gate/digitizer/Singles/quantumEfficiency/setUniqueQE 0.1  But if I don't, the simulation is OK !! I can visualize the energy spectrum, but I'm not sure about the results, what is the default value of the quantum efficiency ?   Here the digitizer part of my macro : 
# DEFINE TRANSFER EFFICIENCY FOR EACH LAYER
/gate/digitizer/Singles/insert transferEfficiency
/gate/digitizer/Singles/transferEfficiency/chooseNewVolume LSOlayer
/gate/digitizer/Singles/transferEfficiency/LSOlayer/setTECoef 0.25
/gate/digitizer/Singles/transferEfficiency/chooseNewVolume GSOlayer
/gate/digitizer/Singles/transferEfficiency/GSOlayer/setTECoef 0.24
 
# DEFINE LIGHT YIELD FOR EACH LAYER
/gate/digitizer/Singles/insert lightYield
/gate/digitizer/Singles/lightYield/chooseNewVolume LSOlayer
/gate/digitizer/Singles/lightYield/LSOlayer/setLightOutput 30000
/gate/digitizer/Singles/lightYield/chooseNewVolume GSOlayer
/gate/digitizer/Singles/lightYield/GSOlayer/setLightOutput 20000
 
# DEFINE INTRINSIC RESOLUTION FOR EACH LAYER
/gate/digitizer/Singles/insert intrinsicResolutionBlurring
/gate/digitizer/Singles/intrinsicResolutionBlurring/chooseNewVolume LSOlayer
/gate/digitizer/Singles/intrinsicResolutionBlurring/LSOlayer/setIntrinsicResolution 0.09
/gate/digitizer/Singles/intrinsicResolutionBlurring/LSOlayer/setEnergyOfReference 511 keV
/gate/digitizer/Singles/intrinsicResolutionBlurring/chooseNewVolume GSOlayer
/gate/digitizer/Singles/intrinsicResolutionBlurring/GSOlayer/setIntrinsicResolution 0.1
/gate/digitizer/Singles/intrinsicResolutionBlurring/GSOlayer/setEnergyOfReference 511 keV
 
# DEFINE QUANTUM EFFICIENCY OF THE PHOTODETECTOR
/gate/digitizer/Singles/insert quantumEfficiency
/gate/digitizer/Singles/quantumEfficiency/chooseQEVolume crystal
/gate/digitizer/Singles/quantumEfficiency/setUniqueQE 0.1 
 Looking forward to your answer
Best regards  Anayisse

Hi
 
Can you post or send me the digitizer part of your macro? How is benchmarkPET performing? It uses blurring.
 
Best regards
