Diffusion-weighted imaging is instrumental in the evaluation of bone quality. However, an interpretation of the data obtained from porous material is complex due to the effects of restricted diffusion. In this study, we are presenting a new restriction diffusion phantom, which was developed for an optimization of acquisition protocols for bone studies. The phantom consists of microscopic-slides separated by glass spheres (~10 μm). The space between slides was filled with water. NMR data were collected and diffusion-properties of the phantom were documented. The proposed phantom can be easily replicated in any laboratory and will assist in investigations of restriction diffusion.
