Circularity and solidity for POL22 with iodine, 4 mL injected at 10 mL/hr in ex vivo bovine liver. The circularity (a, c) and solidity (b, d) based on cone beam CT for MPIN deployed 1 cm (a, b) and deployed 2cm (c, d). Three injections were performed for each device and the values of circularity and solidity are reported for each injection at 1 mL increments (1,2, 3, and 4 mL total injected volumes).
