An optimized human head phantom design for 7 Tesla field strength and its standardized fabrication process is presented. Two different phantom versions were produced: The first gel-only version can be set up quickly and provided realistic T1 and T2 values for its brain, muscle, and lipid compartments. The second version, with its liquid brain compartment containing several metabolites, can be utilized for spectroscopy sequence development. With the 3D model and the validated recipes mimicking head and brain tissue, extensions to other applications can be more easily achieved, such as system characterization, diffusion weighted imaging, or realistic flow phantoms.
