Effect of a poloxamer 407-based thermosensitive gel on minimization of thermal injury to diaphragm during microwave ablation of the liver

Figure 1 Schematic of the experimental set-up used for ex vivo microwave ablations in a 6-well plate. Two swine liver pieces were held at a specific distance, d, which were set to 5 mm or 10 mm. This separation provides a hydrodissection barrier. The ablation needle and temperature probes were positioned in parallel. The distance was always 5 mm between the ablation needle and the primary needle (R1).
