# You may add "--arc 200" to make the scan short or "--proj_iso_x 200" to offset the detector
# Create projections of the phantom file
rtkprojectgeometricphantom -g geometry.xml -o projections.mha --spacing 2 --dimension 256 --phantomfile SheppLogan.txt
# Reconstruct
rtkfdk -p . -r projections.mha -o fdk.mha -g geometry.xml --spacing 2 --dimension 256
# Create a reference volume for comparison
