Researchers at the University of Würzburg have been using 3D printing to prototype kidney models, or kidney phantoms, of different shapes and sizes in order to assess how much radiation is needed for optimal imaging. The goal is to be able to develop patient-specific treatment, and kidneys were chosen for prototyping as they're one of the highest-risk organs in radiation therapy and imaging.
