In this work we propose novel sampling schemes for diffusion MRI required for encoding with objects with more than one directional axis. The presented solution is general and suitable for both axisymmetric and non-axisymmetric encoding schemes. An important feature of the presented sampling schemes is that they can be interleaved and be complimentary. This means that any combination of them can be used to define an isotropic sampling scheme with number of samples: (15, 30, 45, 60, 75, 90).
