Multi-shell diffusion signal recovery from sparse measurements
We present a novel method for reconstruction of the diffusion MRI signal from sparse measurements. A novel function to model the bi-exponential decay of the signal in the radial q-space. Novel algorithmic derivation for spatially smooth signal reconstruction. Extensive experiments done on phantom and in vivo data. Our results show very low error in the recovered signal using at-least 60 samples.
