(color online) Experimental results of sesame oil–water emulsion with 0.35 g/L of poloxamer 188. (a) 2D chemical shift contours, (b) sample picture after 120 min, (c) 1D spectra extracted from 2D map, (d) physical appearances, (e) sesame oil concentration profiles versus time. Concentration profiles at different spatial positions are numerically denoted as 1 to 40 from top to bottom. The spatial resolution is also 0.40 mm/profile.
