DWI and RD of the capillary phantom at 10ºC and 40ºC in diffusion time 50 ms and 800 ms. Each image data is sorted from top to bottom as 6, 12, 25, 50, 100 μm, and free water. DWI outputs the image averaged over 12 axes with the signal value at b0 of each structure size as 100%, and the color bar is displayed at the bottom of the table. RD outputs map after diffusion tensor calculation. DWI, diffusion-weighted imaging; RD, radial diffusivity.
