Summary
A new 3D computer framework with personalized models accurately assesses Total Body Surface Area (TBSA) burned. This method reduces variability and improves accuracy, especially for patients with unique body shapes.
Area of Science:
- Medical Imaging and Simulation
- Computational Anatomy
Background:
- Accurate assessment of Total Body Surface Area (TBSA) burned is critical for effective burn management and fluid resuscitation.
- Traditional methods for TBSA estimation can be subjective and may not account for individual patient morphology, leading to variability.
Purpose of the Study:
- To introduce and validate a novel three-dimensional (3D) computer-based framework utilizing personalized 3D models for precise TBSA assessment.
- To evaluate the impact of morphological variations on TBSA calculations and assess the accuracy of the proposed method.
Main Methods:
- Development of a 3D rendering interface for TBSA calculation.
- Generation of personalized 3D models from anthropometric data using MakeHuman software.
- Validation through preliminary studies on mannequins assessed by volunteers, comparing 3D model accuracy against scans.
Main Results:
- The 3D models built with MakeHuman software showed an absolute error of 3 ± 2.2% compared to scans, with no significant difference.
- Small variations in patient morphology were found to impact TBSA assessment, highlighting the need for personalized models.
- The proposed framework demonstrated improved TBSA assessment with lower variability compared to existing methods.
Conclusions:
- The personalized 3D modeling framework offers a more accurate and less variable approach to TBSA assessment.
- This method is particularly beneficial for patients with specific morphologies (e.g., obese, children) and has the potential to reduce morbidity and mortality.
