| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recent advance of imaging techniques enables to visualize minute lung nodules in the early stage cancer. Although lung nodules are determined using preoperative CT images, the position of the nodules change during surgery due to deaeration. This study was performed to analyze deaeration deformation of animal lungs for development of intraoperative guidance of minute lung cancer. CT images are measured from ex vivo animal lungs with different internal pressures, and surface displacement is analyzed using surface registration. An extension of the Laplacian-based registration algorithm for calculating displacement is proposed in this study. The registration results were evaluated using reference points manually determined on the lung surface and the registration error was within 1.5 mm on average. The relationship between surface and bronchial displacement of ex vivo lungs was also investigated. We found that the magnitude of surface displacement was distributed in an orderly way based on the distance from the pulmonary hilum while it was confirmed that there was a region where the surface displacement was relatively larger than the displacement of the bronchus. | |
