MCS-MRI reconstruction on <i>in vivo</i> brain images using acquired noiselet encoded and Fourier encoded data for different acceleration factors (up/down: phase encodes, left/right: frequency encode).

<p><b>(a)</b>: shows reference image reconstructed from fully sampled Fourier encoded data; <b>(b)-(d)</b>: show images reconstructed using Fourier encoding for acceleration factor of 2.6, 4 and 8 respectively; <b>(e)-(g)</b>: show the difference images using Fourier encoding for acceleration factor of 2.6, 4 and 8 respectively; <b>(h)</b>: shows reference image reconstructed from fully sampled Noiselet encoded data; <b>(i)-(k)</b>: show images reconstructed using noiselet encoding for acceleration factor of 2.6, 4 and 8 respectively; <b>(l)-(n)</b>: show the difference images using noiselet encoding for acceleration factor of 2.6, 4 and 8 respectively. It can be seen from the difference images that noiselet encoding outperforms Fourier encoding on the acquired invivo data. The loss in resolution is clearly visible for Fourier encoding at an acceleration factor of 8.
