(a) The devices used for microwave ablation (MWA) guided by electromagnetic navigation bronchoscopy (ENB) including the ENB working channel catheter (curved‐tip catheter), magnetic probe and customized microwave antenna (with black short needle head), respectively. (b) Magnified image of the three devices. (c) ENB image shows that the working channel catheter has accurately reached a position adjacent to the lesion by guidance of the magnetic probe. MWA guided by ENB in CBCT image. (d) The magnetic probe and working channel catheter were inserted into the bronchus through the bronchoscope. (e) CT image shows that the antenna arrived at the lesion through the working channel catheter before MWA commenced. (f) After MWA was guided by ENB, the area and density of the shadow increased in the location of the lesion.
