Research Abstract

The respiratory motion suppressed three dimensional catheter/guide-wire navigation system has been developed based on three dimensional catheter guiding system for cerebral artery which we had developed before. To apply the guiding system to abdominal artery a respiratory motion suppression technique was necessary. We analyzed respiratory motions of abdominal arteries, and a respiratory motion suppression technique was developed based on the results of the analysis. Additionally, we evaluated reliability of the technique. We found that motions of abdominal artery were correlative well with diaphragm motions and the reliability of the respiratory motion suppression technique was over 90 % in two of the three cases. Thus, this respiratory motion suppress technique is effective for the respiratory motion suppressed three dimensional catheter/guide-wire navigation system.
