摘要：
This study aims to analyze deaeration deformation to develop intraoperative guidance of minute lung nodules. We measured lung CT data from ex-vivo animal lungs with different internal pressures, and analyzed surface displacement using Laplacian-based surface registration. We evaluated the registration results by comparing with reference points determined manually, and confirmed that the registration error was around 1mm. We found that the magnitude of surface displacement is orderly distributed based on the distance from the pulmonary hilum. © 2018, Japan Soc. of Med. Electronics and Biol. Engineering.
