Abstract
Computed tomography (CT) data sets obtained in 14 patients were used in a segmentation
method for virtual bronchoscopy (VB). The method constrained the distance of
propagation of a region-growing algorithm. The resulting three-dimensional bronchial
model was a faithful representation of the source CT data and could be manipulated in
real time at frame rates of one to two frames per second. Preliminary data showed that
90% of bronchi (up to third order) measureable on multiplanar CT reformations were also
measurable at VB. The bronchial diameters measured at VB were within 1 mm of those
measured on multi-planar reconstructions of the CT data.
