3D printing is a fantastic tool for creating prototypes. In parallel, pre-clinical imaging systems have been democratized for longitudinal studies of small animal models. However, for these systems, standardized phantoms for quality control do not exist yet. The aim of the work presented here is to show that phantoms of different shapes and sizes can be 3D printed to characterize preclinical imaging systems or sequences developed by research groups. As an example, images were acquired with a 70μm in plane resolution to study the influence of Cartesian and Radial encodings on the spatial resolution using a mouse dedicated phased array coil at 7T.
