Here we
investigate and demonstrate the effect of changing the encoding time of flow
measurements through a porous media, identifying a region of slow flow and much
faster flow indicating percolation through the media, which vary with encoding time.
Figure 4 a),b) Raw diffusion data
fitted using bi-exponential model for sponge 1 and 2 at the 5 different
diffusion times. C),D) Maps of IVIM and Kurtosis parameters measured at a
diffusion time of 23 ms
separated into the two peaks observed on the flow data.
Figure 2 Phase histograms for
both sponges, imaged at a VENC of ± 0.70 mm/s at 5 different
diffusion times. Histogram plotted with blue bars, Gaussian fit is plotted with
a red curve, peak 1 and 2 means indicated by vertical green and orange lines,
respectively.
