title: [Virtual colonoscopy navigation based on colon division].
abstract: OBJECTIVE
  To develop a virtual navigation mode to enlarge the field of view and decrease the deformation of the visual area.
  
  
  METHODS
  The method was implemented in 3 steps. The entire colon was first divided into consecutive sections, and each section was split into two halves by a plane. The virtual camera was finally assigned onto each half of the sections for navigation.
  
  
  RESULTS
  Adequate subsections were achieved with this method, which also offer an enlarged field of view for the benefit of focal inspection.
  
  
  CONCLUSIONS
  The division navigation mode is suitable for the development of a virtual colonoscopy navigation and diagnosis system.
