Utilizing Pre- and Postoperative CT to Validate an Instrument for Quantifying Pectus Excavatum Severity

Conference paper
Part of the Communications in Computer and Information Science book series (CCIS, volume 645)


An instrument that objectively quantifies a condition’s severity and its improvement after treatment is of great use. This is also the case for pectus excavatum (PE), a congenital chest wall deformity, for which several severity indices have been introduced. This work describes a system that utilizes chest surface scans generated from CT-data or optical scanning to provide a gauge and visualization of chest wall deviations. A validation experiment is conducted to evaluate the fidelity of such an instrument utilizing pre- and postoperative CT scans. Statistical analysis shows the ability of the instrument to accurately recognize changes in the chest surface profile.
