Three-dimensional temporal progression and volumetric distribution of needle injections, 4 mL at 10 mL/h in ex vivo bovine liver. The transparent surface renderings of the volumes at 1 mL increments (1, 2, 3, and 4 mL total injected volumes) based on cone beam CT across different needle devices are superimposed. (a–d) POL22 with iodine and (e–h) iodine alone. Four needles were used: SEHN (a, e), MSHN (b, f), MPIN deployed 1 cm (MPIN-1cm) (c, g), and deployed 2 cm (MPIN-2cm) (d, h) For POL22 with iodine utilizing MPIN-2cm (d), A, B, and C denote the three needle tips.
