Brain cancer stands as one of the most formidable and challenging types of cancer to combat. However, a recent breakthrough in research has introduced a novel approach in its treatment utilizing electric fields. This innovative method, termed electro-capacitive cancer therapy (ECCT), presents a non-invasive alternative devoid of the adverse effects commonly associated with traditional treatments like chemotherapy or radiation. ECCT operates by applying an electric field to the tumor region via a specialized helmet. This field disrupts the growth and multiplication of cancerous cells while leaving healthy cells unaffected.
Key Findings
- Electric Field Distribution in Air Medium: Helmet-1: Average electric field: 1585.72 V/m; highest distribution along the y-axis. Helmet-2: Average electric field: 1413.28 V/m; highest distribution along the x-axis.
- Electric Field Distribution in Grey Matter and Cancer: Helmet-1: Grey matter: 97.43 V/m; Cancer: 80.58 V/m. Optimal for cancers located on the right and bottom. Helmet-2: Grey matter: 64.20 V/m; Cancer: 52.65 V/m. Optimal for cancers located at the top and bottom.
- Compensation Error Analysis: Helmet-1 exhibited higher electric field values and a different distribution pattern compared to Helmet-2. The compensation error varied with cancer location, with Helmet-1 showing more significant differences between simulations and experimental data.
- Field Distribution Patterns: Both sensors effectively measured the electric field distribution, with the 8×8 sensor providing more granular data. The field distribution in the phantom was significantly lower than in the 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, while 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: Wire mesh sensors provide a non-invasive method to accurately measure electric fields in therapeutic settings, ensuring proper ECCT application, particularly in sensitive areas like the brain.
- Voltage Control for Optimized Treatment: Accurate electric field distribution measurement allows for precise control of voltage levels, optimizing therapeutic efficacy and reducing the risk of unintended tissue damage.
- Effectiveness of Wire Mesh Electrodes: Both active and passive wire mesh electrodes measure electric field distribution accurately without altering the pattern, ensuring reliable dosing and targeted treatment.
- Enhanced Treatment Planning: Detailed electric field distribution enables fine-tuning of ECCT parameters, maximizing therapeutic benefits and minimizing exposure to healthy tissues.
- Potential for Broad Clinical Application: The successful use of wire mesh sensors supports their integration into various clinical applications, providing a versatile tool for optimizing electric field-based therapies across different cancer types.
