Book excerpt: The fabrication of anthropomorphic phantoms using 3D-printing technologies is promising for quality assurance of X-ray applications for patient groups with body dimensions that are not adequately represented by conventional phantoms. In this thesis, printing materials for the fused-deposition-modelling technology are characterized for their tissue equivalence and different 3D-printed phantoms are developed. The printed phantoms are validated for application in diagnostic imaging in terms of image contrasts and dose distribution. Printed phantoms are equivalent to conventionally fabricated phantoms. The equivalent fetal dose determined from measurements on a 3D-printed phantom of a pregnant woman and Monte-Carlo simulations on a virtual body model with identical anatomy in the abdominal region validates the method also for the production of individualized phantoms. Thus, 3D-printed-phantoms are suitable for patient-specific dosimetry.
