Radiofrequency identification (RFID) marker placement. Under general anesthesia, cone-beam computed tomography (CBCT)-guided bronchoscopy was performed to place a radiofrequency identification marker as close as possible to the tumor. A bronchoscope was advanced to the target subsegmental bronchus according to virtual bronchoscopic guidance. An RFID delivery catheter was inserted through a working channel and advanced close to the target under CBCT guidance. After fine adjustment of the tip of the delivery catheter proximal to the target, the RFID marker was finally released by rotating the handle of the device. The marker was checked to ensure it was fixed in the peripheral airway under fluoroscopic view, with the expanded anchoring coil. A final CBCT examination was performed to check the positional relationship between the placed RFID marker and the lesion. Under minimally invasive thoracoscopic surgery, operators located the marker by following tone changes that indicated the marker–probe distance, without palpating the lung.
