Fabrication of an anthropomorphic heterogeneous mouse phantom for multimodality medical imaging

open access: yesPhysics in Medicine & Biology, 2018
This work presents a comprehensive methodology for constructing a tissue equivalent mouse phantom using image modeling and 3D printing technology. The phantom can be used in multimodality imaging and irradiation experiments, quality control, and management. Computed tomography (CT) images of a mouse were acquired and imported into 3D modeling software.
