Converting list mode of events to STIR (interfile) sinograms

This implementation concerns data, simulated in GATE for the cylindrical scanner in the framework of Jagiellonian Positron Emission Tomography (J-PET) project.

Prerequisites

• STIR 3.0 (for registered users) or developers’ version
• SAFIR, build with STIR 3.0 (but already integrated with developers’ version, so no need to install).

Simple build:

$ cd /directory-with-repository-files/src/
$ mkdir -p build
$ cd build
$ cmake ../
$ make
$ export PATH=$PWD:$PATH

This will compile two bash executables:

• GenerateCrystalMapJPET – generates file for mapping Cartesian coordinates to IDs of rings and detectors according to scanner geometry.
• ConvertToMUPET – converts ASCII list mode data from GATE simulation into MUPET binary format (with big endian order).

Example of usage

(requires JPETGeometry.par – file containing J-PET geometry parameters.):

$ cd ../../input
$ GenerateCrystalMapJPET -p JPETGeometry.par -o ../crystal_map_jpet.txt
$ ConvertToMUPET -i PSF_384strips_x10_y0_z0 -p JPETGeometry.par -o ../output_x10y0z0.clm.safir
