    Area of Science:

    • Biomedical Engineering
    • Medical Imaging
    • Anatomy

    Background:

    • Accurate measurement of the thoracoabdominal wall is crucial for understanding respiratory mechanics and clinical assessment.
    • Existing methods for measuring trunk shape and volume can be invasive or lack precision.
    • A non-invasive, accurate technique is needed for dynamic assessment of the thoracoabdominal wall.

    Purpose of the Study:

    • To develop and validate a novel optical technique for mapping the size, shape, and dynamic changes of the thoracoabdominal wall.
    • To assess the accuracy of the developed optical technique in measuring linear dimensions, cross-sectional area, and volume.
    • To evaluate the potential clinical applicability of this non-invasive measurement method.

    Main Methods:

    • Projecting a fixed stripe pattern onto the trunk and analyzing contour distortions using digital photography.
    • Utilizing digital encoding of projected light patterns to reconstruct the 3D surface of the thoracoabdominal wall.
    • Testing the technique on rigid objects (globe, cone, dummy torsos) for precise geometric validation.

    Main Results:

    • The optical technique demonstrated high accuracy in measuring linear dimensions (within 0.5 mm).
    • Cross-sectional area was measured with an accuracy of within 5%, and volume with 1.6-3.7% error.
    • The technique successfully mapped the shape and volume of complex 3D surfaces.

    Conclusions:

    • The developed optical technique provides accurate, non-invasive measurement of thoracoabdominal wall shape and volume.
    • The high precision suggests suitability for clinical practice in respiratory monitoring and analysis.
    • This method offers a promising tool for understanding dynamic changes in trunk geometry during breathing.
