• Endobronchial ultrasonography (EBUS) using balloon-embedded probes may cause airway obstruction and requires a rapid scanning procedure. Three-dimensional (3-D) postprocessing of sequential 2-D images may allow detailed studies on a rapidly acquired image volume. We applied a 3-D reconstruction program on EBUS recordings acquired with a radial-scanning probe during a controlled pullback procedure in water-filled airways in five corpses. The aim was to acquire EBUS images under optimized conditions and to test a 3-D software program for postprocessing. Under post mortem conditions, 3-D images were obtained, allowing any-plane imaging and measurements, application of different rendering and visualization algorithms and merging of overlapping volumes.
