Figure 1: Left: preoperative CT image with the patient in supine position. Right: intraoperative CBCT images of the inflated (CBCT inf ) and deflated (CBCT def ) lung with the patient in lateral decubitus position
Figure 2: Overview of the proposed nodule localization frame- frame-work. The process is split into two stages, Phase 1 and Phase 2, that respectively estimate the change of pose deformation then the pneumothorax deformation.
Figure 3: Schematic diagram of the Phase 1 process to estimate the change of pose deformation
