Head-model data and parallel runs

The animated head demos can run under MPI. The BrainWeb animations and vessel imaging example use the external phantom data described below.

Running distributed

mpiexec -n 4 python demos/gallery/caputo_wismer/visual_brainweb_wismer_pulse.py
mpiexec -n 4 python demos/gallery/caputo_wismer/visual_brainweb_wismer_sources.py
mpiexec -n 4 python demos/gallery/caputo_wismer/visual_skullball_wismer_pulse.py
mpiexec -n 4 python demos/gallery/caputo_wismer/visual_skullball_wismer_sources.py
mpiexec -n 4 python demos/gallery/caputo_wismer/visual_brainweb_sensor_imaging.py
mpiexec -n 4 python demos/gallery/caputo_wismer/visual_circular_sensor_imaging.py

The reconstruction optimizer and forward/adjoint wave solves all use the distributed mesh. The skullball variants need no external data. The BrainWeb examples do.

BrainWeb data

BrainWeb data are downloaded and checksum-validated into demos/demo-output/.brainweb/. For manual setup, place the normal model’s gzipped raw-byte file at

demos/demo-output/.brainweb/phantom_1.0mm_normal_crisp.rawb.gz

The phantom’s publication and project page are listed in the references below.
