Schema of four steps in radiofrequency identification (RFID) marking. Step (1): Bronchoscopic placement of the RFID marker, IC tag, into the peripheral bronchus within or adjacent to the tumor using a virtual bronchoscopic navigation technique. Step (2): Computed tomography scan to confirm the exact location of the marker and the three-dimensional relationship between the marker and tumor. Step (3): Intraoperative identification of the marker using a handheld sterile detection probe. Step (4): Real-time monitoring of the tumor location when the lung parenchyma is divided.
