Figure 2From: An in-vitro animal experiment on metal implants’ thermal effect on radiofrequency ablationSymmetrical thermometry in RFA. (a) two thermometric needles were symmetrically inserted for thermometry centering RF electrode. Black arrow: RF electrode. White arrow: graduated thermometric needles, one for test group, the other for control group. (b) a panorama of thermometry in RFA. White arrow: digital thermometer. Black arrow: cool-tip RF generator.Back to article page
