Abstract:
BACKGROUND AND OBJECTIVES: This study was conducted to gather basic information of virtual endoscopy (VE) in detecting and gaining information of tracheoesophageal foreign body (FB) models. SUBJECTS AND METHOD: The chest model was made using a PVC bottle, a plastic tube, a vinyl tube and a plaster. Fish bones, shells and plastic toys were used to simulate foreign bodies of tracheoesophageal model. CT of the chest model was reconstructed three-dimensionally by using the Rapidia software for virtual endoscopy of foreign body models. The virtual endoscopic images were compared with real foreign body materials as to shape, size, location and orientation. RESULTS: Tracheoesophageal FB models were easily made. CT data gave good 3D images and virtual endoscopic images showed realistic foreign body materials. CONCLUSION: The results indicate the usefulness of converting CT data into virtual endoscopic images so as to help in the diagnosis of foreign bodies.
