Area of Science:

  • Biomedical Engineering
  • Medical Physics

Background:

  • Microwave hyperthermia is a promising cancer treatment modality.
  • Effective focusing of microwave energy is crucial for targeted tumor ablation.
  • Existing antenna systems require further optimization for clinical application.

Purpose of the Study:

  • To design, analyze, and evaluate a novel antenna array system for microwave hyperthermia.
  • To assess the system's focusing capabilities using the time-reversal principle.
  • To determine the optimal configuration for precise energy deposition in phantom models.

Main Methods:

  • Calculated power absorption distributions in homogeneous and inhomogeneous cylindrical phantoms (500-900 MHz).
  • Analyzed two antenna array setups (12 and 16 antennas) using iso-Specific Absorption Rate (SAR) contours (50%, 75%, 90%).

  • Quantitatively evaluated results using average power absorption ratio and remaining tissue maximum index.

    • Main Results:

    • Achieved the sharpest focusing area (151 mm², 90% iso-SAR) with 16 antennas at 900 MHz.
    • Obtained the largest focusing area (280 mm², 90% iso-SAR) with 16 antennas at 500 MHz.
    • Successfully steered the SAR focus radially in a neck phantom, achieving a 43 mm² 90% iso-SAR focus-width.

    Conclusions:

    • Confirms the feasibility of time-reversal focusing methods for microwave hyperthermia.
    • The developed antenna array system is suitable for further development in treating head and neck tumors.
    • The system shows potential for extremities applications in hyperthermia treatment.
