Ultimately, it could revolutionize how we utilize electric fields in cancer treatment, paving the way for significant improvements in patient care.
Key Findings
- Voltage and Electric Field Distribution: Wire Mesh Sensor 3×3 showed distinct voltage patterns for air and phantom mediums with higher electric field values in air. Wire Mesh Sensor 8×8 provided higher resolution and more detailed electric field distribution, with clear differentiation between air and phantom mediums.
- Simulation and Experimental Validation: Simulations confirmed significant differences in electric field distribution between air and phantom. Experimental results consistent with simulations, validating the accuracy of wire mesh sensors. The 8×8 sensor demonstrated superior resolution and accuracy compared to the 3×3 sensor.
- Field Distribution Patterns: Both sensors effectively measured electric field distribution, with the 8×8 sensor providing more granular data. The electric field distribution in the phantom was significantly lower than in air, highlighting the impact of tissue permittivity.
- Resolution and Accuracy: The 8×8 sensor achieved an 82.42% reduction in electric field values in the phantom compared to air. The 3×3 sensor showed a 61.8% reduction. Bilinear interpolation improved the resolution, making the 8×8 sensor preferable for precise measurements.
Clinical Implications
- Non-Invasive and Precise Measurement: The wire mesh sensors provide a non-invasive method to accurately measure electric fields in therapeutic settings. This precision ensures that ECCT is applied correctly, particularly in sensitive areas such as the brain, optimizing therapeutic outcomes and minimizing side effects.
- Voltage Control for Optimized Treatment: The findings emphasize the importance of voltage control in ECCT. Ensuring stable and appropriate voltage levels can optimize therapeutic efficacy, effectively inhibiting cancer cell growth while reducing the risk of unintended tissue damage.
- Effectiveness of Wire Mesh Electrodes: Both active and passive wire mesh electrodes accurately measure electric field distribution without altering the pattern. This reliability is crucial for ensuring accurate dosing and targeted treatment, which is essential for effective cancer therapy.
- Enhanced Treatment Planning: Understanding the electric field distribution within the body model allows for fine-tuning ECCT parameters. This knowledge enables clinicians to maximize therapeutic benefits by targeting cancer cells more effectively and minimizing exposure to healthy tissues.
- Potential for Broad Clinical Application: The successful use of wire mesh sensors to analyze electric field distribution supports their integration into broader clinical applications. This technology can be used in various cancer treatments beyond brain cancer, providing a versatile tool for optimizing electric field-based therapies across different cancer types.
