Comparison of the diffusion weighted data for a slice of the double-shell experimental dataset. The left row shows the data at the b = 800s/mm²-shell, the right row at the b = 2000s/mm²-shell. The grayscale of the images is set to a maximal image contrast. a) Original noisy data, b) msPOAS reconstruction, c) mean of 10 repeated measurements of the considered diffusion weighted images, d) reconstruction using POAS on each shell separately, e) reconstruction using a non-local means (NLM) method (Wiest-Daesslé et al., 2008), and f) reconstruction using the method described in Haldar et al. (2013), Varadarajan and Haldar (2013).
