Area of Science:

  • Medical Physics
  • Biomedical Engineering
  • Oncology

Background:

  • Optimal hyperthermia treatment for large, superficial tumors requires advanced applicators.
  • Existing applicators struggle with body contour conformity and localized power adjustments.
  • Tissue inhomogeneities and blood flow variations cause temperature nonuniformities.

Purpose of the Study:

  • To develop and clinically test 915 MHz microstrip array applicators for hyperthermia treatment.
  • To address the need for applicators that conform to body contours.
  • To enable local adjustment of power deposition for uniform heating.

Main Methods:

  • Development of a series of 915 MHz microstrip array applicators.
  • Clinical testing of the developed applicators.

  • Measurements using tissue-equivalent phantoms.
  • Analysis of clinical experiences.

    • Main Results:

    • Successful development and clinical testing of conformable microstrip array applicators.
    • Demonstrated ability to locally alter power deposition patterns.
    • Measurements confirmed performance in phantom studies.
    • Clinical experience highlights practical device considerations.

    Conclusions:

    • The developed 915 MHz microstrip array applicators meet the criteria for optimal hyperthermia treatment of large superficial tumors.
    • These applicators offer improved temperature control by addressing tissue variations.
    • Clinical testing and phantom measurements support their practical application.
