A new adaptive temperature control system for superficial hyperthermia using microstrip antenna arrays ensures precise temperature regulation. This system effectively manages power, even with complex antenna arrays and cooling changes, minimizing complications.

Area of Science:

  • Biomedical Engineering
  • Thermal Therapy
  • Medical Devices

Background:

  • Superficial hyperthermia treatments require precise temperature control for efficacy and safety.
  • Microstrip antenna arrays offer potential for large-area thermal therapy but present control challenges due to antenna coupling.

Purpose of the Study:

  • To develop and validate an adaptive temperature control system for microstrip antenna arrays in superficial hyperthermia.
  • To ensure accurate and stable temperature distribution during treatment, minimizing complications.

Main Methods:

  • A recursive algorithm based on a first-order difference equation model was developed for rapid power updating.
  • Surface and depth temperature feedback from antenna elements and additional probes were utilized.
  • Experiments were conducted using a tissue-equivalent phantom with dynamic differential cooling.
