title: [The clinical application of stereography in laryngology with "the three-dimensional reconstruction system of medical faultage photograph"].
abstract: OBJECTIVE
  To study the value of the clinical application of stereography in laryngology.
  
  
  METHODS
  Taken by Microtek E6 scanner, the CT faultage images were inputted in personal computer and reconstructed to a three-dimensional stereograph by "the three-dimensional reconstruction system of medical faultage photograph". The software was compiled using IDL5.2, a complete, integrated software environment for data analysis, visualization and application.
  
  
  RESULTS
  The three-dimensional laryngeal graph could be incised in random, displayed in optional degree, and was rotatable, semitransparent and measurable. The tumor could identified be identified by a special color and revealed through translucent parenchyma and cartilage. Reconstruction stereographs of laryngeal and hypopharyngeal cancer of 26 patients were investigated.
  
  
  CONCLUSIONS
  It is convenient for popularization because the three-reconstruction process is built on a personal computer without the need of any equipment for image acceleration. It is very helpful for ENT surgeon to define the range of the tumor, to fix on surgical pattern accurately and to anticipate the operational course.
