Figure 6.
(A) Photograph of the 18 mm inner-diameter water-filled spherical dispersion phantom, with hyperpolarized water entering from the bottom left and exiting on the bottom right. (B–F) 1.5 T coronal MR images of the spherical dispersion phantom, where the coronal plane is the same plane as the page. Slice 2 roughly corresponds to the vertical center of the sphere. The enhanced water displays jet-like behavior as it crosses the phantom until it reaches the opposite wall. The flow rate was 1.5 mL/min. Images are available in color online.
