The most important quality control criterions in Magnetic Resonance Imaging (MRI) are represented by the contrast-to-noise-ratio (CNR) and the spatial resolution. This report presents the design, a prototype object, an exemplary MRI evaluation, qualitative results and quantitation of the spatial resolution up to microscopic scale beyond pixel-size characterization. The phantom is manufactured using Deep X-Ray Lithography (DXRL) at the Synchrotron radiation source KARA (Karlsruhe Research Accelerator) for obtaining highly anisotropic tube type cavities for getting the Point-Spread-Function (PSF) and Modulation Transfer Function (MTF) in MR-µ-imaging ranging from d=256µm down to d≈4 µm.
