The fiber ODFs obtained by applying diffusion deconvolution and diffusion decomposition to QBI, DSI, and GQI.

<p>Each of the methods reconstructs diffusion ODF from shell, grid, and two-shell sampling schemes, respectively. Both diffusion deconvolution and diffusion decomposition can be equally applied to QBI, DSI, and GQI to improve their ability to resolve crossing fibers, but the fiber ODFs obtained from deconvolution shows blunt lobes with fluctuating baseline, whereas those from decomposition show sharp spikes with clean baseline, suggesting that diffusion decomposition can achieve better sensitivity and specificity in resolving crossing fibers.
