ECG Electrode Localization: 3D DS Camera System for Use in Diverse Clinical Environments

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Computational Biology

Background:

• Digital twin models of patients are increasingly used for personalized medicine.
• Accurate electrocardiogram (ECG) electrode placement is crucial for cardiac diagnostics.
• Current methods for electrode localization have limitations in precision and time efficiency.

Purpose of the Study:

• To develop and evaluate a novel 3D depth-sensing camera system for precise ECG electrode localization.
• To provide a faster and more accurate alternative to existing manual methods for electrode placement.
• To assess the system's performance in a clinical environment.

Main Methods:

• A 3D depth-sensing camera system was developed to capture electrode positions.
• The system was tested in a clinical setting, recording 67 electrode positions on a patient's chest.
• Positional accuracy was compared against manually placed markers on 3D views.

Main Results:

• The developed 3D camera system achieved an average positional deviation of 2.0 mm ±1.5 mm.
• The system demonstrated reasonable positional precision even under challenging clinical conditions.
• The new system offers a significant improvement over manual localization methods.

Conclusions:

• The 3D depth-sensing camera system provides a precise and efficient method for ECG electrode localization.
• This technology can enhance the development of patient-specific digital twins for improved cardiac diagnostics and treatment.
• The system's performance in clinical settings validates its potential for widespread adoption in personalized medicine.
