Abstract

We present a straight-forward strategy for how to process anthropomorphic phantoms to enable simulations of propagation-based phase-contrast X-ray imaging (PBI). PBI requires sampling of a few micrometers which results in few TB of storage for a centimeter-sized model. With long propagation distances the thickness of each material in the X-ray direction is enough to perform accurate simulations. By using a boundary-preserving upsampling procedure on a coarsely voxelated phantom followed by a summation in the X-ray direction thickness maps with high sampling can be built. This opens up for improved imaging optimization and virtual clinical trials.
