Examples 8: Voxelized Source¶

The voxelized source is available since GGEMS v1.3.

python voxelized_source.py [-h] [-d DEVICE] [-b BALANCE] [-s SEED] [-v VERBOSE] [-e] [-p NPARTICLESGL] [-c] [-n NPARTICLES]
-h, --help            show this help message and exit
-d, --device DEVICE   OpenCL device (all, cpu, gpu, gpu_nvidia, gpu_intel, gpu_amd, X;Y;Z...) (default: 0)
-b, --balance BALANCE
                      X;Y;Z... Balance computation for device if many devices are selected. -b "0.5;0.5" means 50 % of computation on device 0, and 50 % of computation on device 1 (default: None)
-s, --seed SEED       Seed of pseudo generator number (default: 777)
-v, --verbose VERBOSE
                      Set level of verbosity (default: 0)
-e, --nogl            Disable OpenGL (default: True)
-p, --nparticlesgl NPARTICLESGL
                      Number of displayed primary particles on OpenGL window (max: 65536) (default: 256)
-c, --drawgeom        Draw geometry only on OpenGL window (default: False)
-n, --nparticles NPARTICLES
                      Number of particles (default: 1000000)

A 177Lu voxelized source example is provided

vox_source = GGEMSVoxelizedSource('vox_source')
vox_source.set_phantom_source('data/phantom_src.mhd')
vox_source.set_number_of_particles(number_of_particles)
vox_source.set_source_particle_type('gamma')
vox_source.set_position(0.0, 0.0, 0.0, 'mm')
