From Simulation in GATE to a Final Multiring Albira PET/SPECT/CT Camera 17

final product. Depth of interaction correction was introduced as well. For future versions, inclusion of all coincidences, also from the tapered region of the crystal would be available, as it considerably increases the detector total efficiency.

#### **10.1 Appendix 1: Albira macro files listing for 3 ring scanner Gate simulation**

Note that that all files must be in one directory. All lines in \*.mac files end with Linux LF end of line character only. In the listing above, long lines are continued in the following one, with the first having hanging indent. Macro is based on benchmarkPET.mac provided with Gate 3.0.0 and Gate 6.0 (Jan et al. 2004).
