From: An in-vitro animal experiment on metal implants’ thermal effect on radiofrequency ablation
Modeling and grouping. (a) vertical multi-pin array for test group. Black arrow: RF electrode. White arrow: nine epidural needles used for the implantation in square array (side length of 2.0 cm). (b) Section to reveal metal implants embedded in liver tissue constructing a cuboid. Black arrow: RF electrode, 1.0 cm away from metal implants model. White arrow: test group with 125I seeds. (c) Section of liver after RFA. White arrow: test group (containing silver clips). Black arrow: control group. The ablation scopes of the both groups had no differences.
