New Methods for Imaging Evaluation of Chest Wall Deformities

Area of Science:

• Medical imaging
• Biomechanical engineering
• Orthopedics

Background:

• Chest wall deformities require objective assessment methods.
• Current imaging techniques may involve radiation or be invasive.
• Accurate evaluation is crucial for treatment planning and monitoring.

Purpose of the Study:

• To develop and evaluate an external 3D scanner for noninvasive imaging of chest wall deformities.
• To establish objective assessment and severity evaluation using external indexes.
• To validate the scanner's effectiveness in diagnosing and following up patients.

Main Methods:

• A prospective study included 100 pediatric and young adult patients with pectus excavatum or pectus carinatum.
• External 3D scanning was performed monthly for non-operative cases and pre/post-surgery for operative cases.
• Correlations between CT-derived Haller index and externally derived index were analyzed (r=0.83).

Main Results:

• The OrtenBodyOne scanner utilizes depth sensors and computer vision techniques.
• The system allows for objective assessment, 3D reconstruction, and severity evaluation.
• A strong correlation was found between CT-based and external Haller indexes.

Conclusions:

• External 3D scanning is an effective, objective, and radiation-free diagnostic tool.
• It enables reliable follow-up for patients with chest wall deformities.
• Externally measured indexes accurately reflect deformity severity and treatment outcomes.
