Abstract :
A non-radiological method of visualizing the path of a colonoscope using a chain of electromagnetic sensor coils along the biopsy channel of the instrument has been developed. The electromagnetic imaging system has been introduced as an aid to colonoscopy, and reveals a great potential for assisting endoscopists. There is an existing model available on the market by Olympus, ScopeGuide; however, due to cost consideration and other factors concerned, some hospitals may not want to replace existing instruments. This paper discusses about the possibility of using a commercially available electromagnetic tracking system, the Northern Digital Aurora system and presents a simple algorithm employed to find a representation of the colonoscope path. A possibility of reducing the amount of sensor coils used in existing model is also discussed. The visual guidance is expected to provide the user with a sense of assurance, which is often missing in the navigation of colonoscope. The work may be useful in locating the exact position when a lesion is found during the procedure, and to identify a loop when it is formed. It may also be useful as a navigational aid in colonoscopy training and teaching purposes.
