[Gate-users] How to set the timing resolution of Two-layer detector

[Maxime Toussaint]

Greetings,

To the best of my knowledge, the Single digitizer treat every crystal equal. Thus, you cannot use Gate as-is to set multiple values of timing resolution. You must either modify Gate to enable this feature or add the timing blur after the simulation.

Bests,
Maxime Toussaint

Objet : [Gate-users] How to set the timing resolution of Two-layer detector


Dear GATE users



I'm designing a two-layer PET detector.

I know the time resolution for each crystal.

The time resolution of the crystal at the bottom is 140.8 ps and the crystal at the top is 244.0 ps.

How do I set the digitizer?

Below is the digitizer in my macro file.



----------------------------------------------------------------------

# D I G I T I Z E R

/gate/digitizer/Singles/insert adder

/gate/digitizer/Singles/insert readout

/gate/digitizer/Singles/readout/setDepth 4



/gate/digitizer/Singles/insert blurring

/gate/digitizer/Singles/blurring/setLaw linear

/gate/digitizer/Singles/blurring/linear/setResolution 0.15

/gate/digitizer/Singles/blurring/linear/setEnergyOfReference 511. keV

/gate/digitizer/Singles/thresholder/setThreshold 450. keV

/gate/digitizer/Singles/insert upholder

/gate/digitizer/Singles/upholder/setUphold 650. keV

???????????????????????????????????????????

I need your help.



Thank you.
