Combining optical coherence tomography (OCT) and pulse speckle imaging (PSI) accurately classifies burn depth. This dual-modal imaging approach improves diagnostic sensitivity for burn wound assessment.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Dermatology

Background:

  • Current burn depth assessment relies on subjective methods or single imaging modalities, limiting diagnostic accuracy.
  • Non-contact imaging techniques like OCT and PSI show potential for improved burn visualization.
  • Integrating data from multiple imaging modalities may enhance diagnostic sensitivity.

Purpose of the Study:

  • To develop and validate a dual-modal imaging approach combining OCT and PSI for classifying burn depth.
  • To improve the sensitivity and accuracy of burn diagnosis compared to single-modality assessments.

Main Methods:

  • Developed algorithms to integrate and visualize skin structures from OCT and PSI data.
  • Employed a porcine burn model to test the dual-modal fusion approach.

  • Validated computer-derived burn depth data using immunohistochemical analysis.

    • Main Results:

    • The fused OCT and PSI modalities achieved an ROC-AUC of 0.87 (p<0.001) in classifying burn types (superficial, partial-thickness, full-thickness) one hour post-injury.
    • Demonstrated the utility of the dual-modal fusion approach in a porcine model.
    • Computer-derived data correlated well with immunohistochemical validation.

    Conclusions:

    • The combined OCT and PSI imaging system offers a promising, non-contact method for accurate burn depth classification.
    • This dual-modal fusion approach significantly enhances diagnostic sensitivity for burn wound assessment.
    • Further studies are underway to assess the system's feasibility for longitudinal wound tracking.
