Electromagnetic navigational bronchoscopic and transthoracic biopsy

Panel A shows concurrent computed tomographic and virtual images displayed to the bronchoscopist during electromagnetic navigational bronchoscopy. Real-time images and virtual images together guide the bronchoscopist to the peripheral target lesion for biopsy. Panel B shows similar computed tomographic images during navigation of a transthoracic needle to biopsy a target peripheral nodule. The biopsy needle is directed so that it is present in the lesion in the axial, coronal, and oblique CT views to ensure the best yield.
