In this work, we successfully quantified the Reynolds stress tensor (RST) in a well-known fluid-dynamic test case: the flow over periodic hills. This test case was chosen because the turbulence in this kind of flow is strongly inhomogeneous and anisotropic, representing a challenging measurement task. The results indicate, in analogy to intravoxel velocity standard deviation (IVSD) mapping, that RST quantification is highly susceptible to the applied $$$m_1^{enc}~$$$value. Furthermore, RST mapping inherently requires a higher dynamic range compared to IVSD mapping, since the shear stresses are typically much lower than the normal stresses.
