Conditions

Any disease or indication that requires CBCT imaging to aid in diagnosis or intervention in interventional medicine.

Interventions

Gold Standard:Concurrent high-resolution diagnostic CT images of the patients
Index test:AI-restored CBCT images corrected by the Clear-CBCT algorithm

Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1.Patients who underwent CBCT scanning of the head, chest, or abdomen under DSA, and concurrently completed high-resolution diagnostic CT scanning; 2.CBCT images exhibiting varying degrees of motion artifacts (from mild to severe); 3.Diagnostic CT images are clear with no obvious artifacts or distortion, suitable to serve as the anatomical gold standard; 4.Complete clinical data with no missing key information; 5.No specific restrictions on age or gender; absence of comorbidities that might interfere with image evaluation, such as severe hepatic or renal dysfunction, or psychiatric disorders.

Exclusion criteria

Exclusion criteria: 1.Extremely poor image quality of either CBCT or diagnostic CT, precluding artifact evaluation and anatomical comparison; 2.Time interval between the CBCT and diagnostic CT scans exceeding 1 week, posing a risk of anatomical changes; 3.Patients with other severe concurrent diseases that may affect lesion visualization and evaluation; 4.Incomplete imaging data or missing key information, making it impossible to complete study-related evaluations; 5.CBCT equipment not calibrated according to quality control standards, leading to equipment-related errors in the imaging data.
