Example 1

Simple Cylindrical PET with 20 x 20 block, 5x5 crystal, LSO and BGO layer, 4 rings.

  • No phantom.
  • Physics list: emstandard_opt4
  • Digitizer: adder, NO readout, threshold, coinc 10 ns
  • Source: back to back 511 keV, half-life of 1223 sec (C11)
Gate mac/main1.mac

This will generate output/output1.root with hits, singles and coincidences

Offline digitizer

GateDigit_hits_digitizer output/output1.root output/output1-singles.root mac/main1_offline_digitizer.mac

This will generate output/output1-singles.root with the singles. There is an error message since there are branches not found since it is designed for CCMod data and those branches are missing here

Offline sorter

GateDigit_singles_sorter output/output1-singles.root output/output1-coincCCMod.root mac/main1_offline_sorter.mac abs
GateDigit_singles_sorter output/output1.root    output/output1-coincCCMod.root  mac/main1_offline_sorter.mac abs

We can generate the coincidences either from the singles of simulation stored in output/output1.root or from the offline generated singles output/output1-singles.root This will generate output/output1-coincCCMod.root with the coincidences

Convert CCMod coincidences into PET/SPECT coincidences format ( On branch anetxe offlineDigitizer, not yet in OpenGate)

 Convert_CCMod2PETCoinc output/output1-coincCCMod.root output/output1-coinc.root  mac/main1_offline_geom.mac

test with gam_gate. test_main.py

Example 1.b

Simple Cylindrical PET with 20 x 20 block, 5x5 crystal, LSO and BGO layer, 4 rings.

  • No phantom.
  • Physics list: emstandard_opt4
  • Digitizer: adder, readout (depth 1 or head), threshold, coinc 10 ns
  • Source: back to back 511 keV, half-life of 1223 sec (C11)
Gate mac/main1b.mac

This will generate output/output1b.root with hits, singles and coincidences
