Mobile CBCT Three-Dimensional Scanning: Mobile CBCT Three-Dimensional Scanning
Study summary
The purpose of this study is to evaluate the clinical value of mobile 4D CBCT technology in the diagnosis and treatment of peripheral pulmonary lesions and to validate its intraoperative dynamic three-dimensional CT imaging capability.

Inclusion Criteria:
1. Age \>18 years old.
2. Patients whose chest CT scans indicate the presence of peripheral pulmonary lesions and require further diagnosis via transbronchial lung biopsy (TBLB).
3. Lesion size: 8 mm \< longest diameter of lesion ≤ 50 mm.
4. Understands the study and has provided signed informed consent.
Exclusion Criteria:
1. Contraindications to bronchoscopy are present.
2. Severe cardiopulmonary dysfunction or other conditions that may increase surgical risk.
3. The investigator considers that the patient has other conditions which make them unsuitable for participation in this study.
Primary outcome measure(s)
RMSE（Root Mean Squared Error） — 1 year RMSE (Root Mean Square Error): A commonly used metric for measuring the difference between predicted values and actual values. It is applicable in regression problems and image quality assessment. A smaller RMSE value indicates more accurate predictions, with 0 representing perfect accuracy, while a larger value indicates greater error.
SSIM (Structural Similarity ) — 1 year SSIM (Structural Similarity ): A metric used to measure the similarity between two images, comparing them across three dimensions: luminance, contrast, and structure. The SSIM value ranges from \[-1, 1\], where 1 indicates that the two images are identical, and 0 or negative values indicate complete dissimilarity.
