Three-dimensional imaging of the lung in vivo: work in progress.
It has previously been demonstrated that three-dimensional (3D) displays of the lung and bronchial tree can be generated from computed tomography (CT) scans of lung specimens. Subsequent refinement of the reconstruction algorithms has allowed high-resolution reconstructions of lungs in vivo. With the introduction of low-dose CT scan protocols, use of the technique may become more common in the radiologic community. The many potential clinical applications for 3D imaging of the lung include an aid to bronchoscopy and improved surgical planning. We present the technical details for 3D imaging of the lungs in vivo as well as three representative case studies.
