| Research Abstract |
We have developed a surgical navigation system called "TAAA Navigator", which is especially designed for aortic vascular surgery. The system consists of functions that are based on our recent studies : a multipoint-based registration algorithm on bone structure, a correction method of tissue thickness, a reference marker system tracking bed position, and a target detection method using both external and internal points on body. In this paper, we report a newly applied registration algorithm to correct errors derived from the tissue thickness of patients. A model formula was provided to analyze error factors on tissue thickness. The error components were divided into the average value and the deviation value. In this algorithm, the average value was regarded as the offset of tissue thickness and the deviation value was as the weight of the measurement. A phantom examination showed the offset was effective. To reveal the efficacy of the weight, further discussion would be needed.
