MRI gelatin phantom and slice localization. (A) Cells in Ultem wells were mounted in one hemisphere of a 9 cm spherical phantom and overlaid with 4% gelatin/PBS. In the final assembly, this hemisphere was secured to a gelatin-only hemisphere to give a 9 cm sphere overall. A plastic marker was used as an indicator of sample layout [37]. (B) To acquire MR images, the cell phantom was placed in a knee coil. Yellow lines in the locator image indicate the 3 mm slice thickness through the samples.
