Technique for Localization of Pulmonary Nodules Using Spy Thoracoscope System


This study will determine the feasibility of the novel Indocyanine Green (ICG) fluorescence localization technique with a Laser fluorescence thoracoscope system.

The primary objective of this study is to prove the validity and safety of our novel fluorescent localization method with utilized ICG and novel near infra-red fluorescence videoscope system.
