Colonoscope tracking or navigation system that navigates a physician to polyp positions during a colonoscope insertion is required to reduce complications such as colon perforation. ...
However, large tracking errors were observed due to colon deformations occurred during colonoscope insertions. Such deformations make the registration difficult. ...
A colonoscope tracking method is one of fundamental function in the navigation systems. It estimates the colonoscope position in the colon. ...

Colonoscope tracking or a navigation system that navigates physician to polyp positions is needed to reduce such complications as colon perforation. ...
Previous tracking methods caused large tracking errors at the transverse and sigmoid colons because these areas largely deform during colonoscope insertion. ...
A colonoscope navigation system is needed that leads a physician to the polyp position. To develop a colonoscope navigation system, a colonoscope tracking method must be developed. ...
