During radiofrequency ablation, electrodes are placed in the patient's lung cancer using CT guidance. For more information see Radiofrequency Ablation of Lung Tumors.
Radiofrequency ablation needle devices that contain multiple curved, retractable electrodes. The electrodes are kept inside the needle until its tip is positioned within a tumor.
The radiofrequency generator. Connected by insulated wires to the needle electrode, the generator produces alternating electrical current in the range of radiofrequency waves.
Closeup of retractable electrodes used in radiofrequency ablation. A generator, shown in the background, provides electrical current for the electrodes.
