Background:

  • Hyperthermia enhances chemotherapy and radiotherapy efficacy for malignant tissues.
  • Accurate simulation is crucial for optimizing hyperthermia treatment planning.

Purpose of the Study:

  • Introduce a real-time hyperthermia simulator (RTHS) using the finite element method (FEM).
  • Develop a cost-effective and computationally efficient tool for hyperthermia treatment optimization.

Main Methods:

  • Developed an RTHS in MATLAB App Designer with an annular phased array (APA) of dipole antennas.
  • Employed a convex optimization algorithm (COA) for precise temperature control at target locations.
  • Validated RTHS performance against COMSOL and Sim4Life software.

Main Results:

  • RTHS simulations showed high consistency with commercial FEM and FDTD software.
  • Demonstrated effectiveness across various target positions in homogeneous and heterogeneous phantom models.
  • Achieved high accuracy (93-96%) with reduced computational time and cost-effectiveness.

Conclusions:

  • The RTHS is a reliable, cost-effective tool for hyperthermia treatment optimization.
  • Its reduced computational demands make it a practical option for clinical applications.
  • Further mesh refinement can enhance accuracy at the expense of increased computation time.
