This study plans to collect approximately 20 localization cases from multiple centers within our hospital. Initially, two sets of preoperative simulated CT scans (at end-inhalation and end-exhalation) will be performed in the CT suite to construct a usable model of the surgical posture and the lesion. Subsequently, in the hybrid operating room, a digital twin model will be applied to the patient using a metaverse platform. Guided by virtual localization lines, percutaneous injection of Patent Blue dye will be carried out at end-exhalation for accurate marking of the lesion. Immediately after the injection, intraoperative CT within the hybrid operating room will be used to verify the localization. If the accuracy is suboptimal (with a deviation greater than 2 cm), standard CT-guided Patent Blue dye localization will be performed as a supplementary measure to complete the localization and proceed with surgery.
