During radial endobronchial ultrasound (EBUS) bronchoscopy for peripheral pulmonary lesions, a portable cone-beam CT system (mobile C-arm, Cios Spin
Siemens Healthcare) is used to confirm the position of the lesion and biopsy tool. One scan is performed, lasting approximately 30 seconds. Reconstructed images are reviewed immediately, and bronchosc
