ABSTRACT：A nodule in the right middle lobe of the lung was treated by a combination of cone-beam CT， three-dimensional registration for fusion imaging，and electromagnetic navigationbronchoscopy-guided thermal ablation.The procedure lasted for90min，with no significant bleeding observed underthe bronchoscope.The total radiation dose during theoperation was 384 mGy.The patient recovered wellpostoperatively，withonlyasmall amount of blood in the sputum and no pneumothorax or other complications.A follow-up chest CTon the first day post operation showed that the ablation area completely covered the lesion，and the patient was discharged successfully.
