Diffusion-weighted magnetic resonance imaging in brain white matter probes\ntissue microstructure and allows for the estimation of compartmental diffusion\nparameters. Recently, it became apparent that traditional single-direction\ndiffusion encodings are not fully sufficient to resolve the white matter\ncompartmental diffusivities. Multiple diffusion encodings have been suggested\nto make the problem less ambiguous, however, it still remained unclear whether\nsuch protocols would completely solve the problem. Here, we constructively\nprove that a combination of linear and planar diffusion encodings is enough to\ndetermine the parameters of the three compartment white matter model.\n
