| Research Abstract |
Intraoperative 3-D image acquisition and augmented reality for laparoscopic surgical navigation system
1.Intraoperative tracker calibration using a magneto-optic hybrid tracker for 3-D ultrasound-based navigation in laparoscopic surgery (2004)
The accuracy of magnetic trackers is affected by magnetic field distortion that results from the close proximity of metal objects and electronic equipment, which is unavoidable in the operating room. We developed a calibration method for intraoperative magnetic distortion that can be applied to laparoscopic 3-D US data acquisition.
2.In vivo experiment (2004)
We evaluated the accuracy of laparoscopic 3-D US reconstruction by animal experiments. Using a pig, calibration data and 3-D US volumes were acquired under laparoscopic control. A wedge-shaped landmark attached to the distal end of the holder was placed dorsal to the pig liver, and the landmark holder was fixed by the endoscopic holder. The positional error caused by magnetic distortion was redu

ced to 2.9 mm.
3.Estimation of intraoperative lung deformation for computer assisted thoracoscopic surgery (2005〜2007)
In the thoracoscopic surgery, predicting the cancer position based on intraoperative thoracoscopic images and preoperative CT images often becomes a difficult task because the lung collapse causes significantly large deformation of the lung. We propose a CT-based thoracoscopic surgical navigation system, involving the intraoperative correction of large large deformation. Animal and clinical experiments were performed to evaluate the prediction accuracy of the cancer position.
4.Sentinel node navigation system (2005〜2007)
After the gastric submucosal injection of contrast enhance agent (Super-Paramagnetic Iron Oxide: SPIO) for magnetic resonance imaging (MRI), optimal conditions were investigated for sentinel node navigation system for gastric cancer.
5.Navigation system for ureter in rectosigmoid resection (2006〜2007)
To avoid the intraoperative injury of ureters, we have developed the navigation system for ureters which were superimposed onto live endoscopic images intraoperatively. Less
