    Microwave thermography shows promise for breast cancer detection, matching infrared thermography's accuracy. Combining both methods further improves detection rates, offering a potential advancement in medical diagnostics.

    Area of Science:

    • Biomedical Engineering
    • Medical Imaging
    • Electromagnetics

    Background:

    • Thermography utilizes thermal radiation for imaging.
    • Microwave thermography offers a non-invasive approach to detect subsurface temperature variations.
    • Understanding its principles and limitations is crucial for medical applications.

    Purpose of the Study:

    • To review the principles, operation, limitations, and medical potential of microwave thermography.
    • To present findings on breast cancer detection using microwave thermography at specific frequencies.
    • To evaluate the combined efficacy of microwave and infrared thermography.

    Main Methods:

    • Review of physical principles and operational methods of microwave thermography.
    • Experimental study of breast cancer detection at 1.3 and 3.3 GHz.

  • Analysis of detection rates based on frequency, time, tumor depth, and size.
  • Comparative analysis with infrared thermography.

    • Main Results:

    • Microwave thermography at 1.3 GHz achieved a true-positive rate of 0.76 with a true-negative rate of 0.63 for breast cancer detection.
    • Detection performance was analyzed concerning frequency, time, tumor depth, and size.
    • Combining microwave and infrared thermography increased the true-positive rate by approximately 0.1.

    Conclusions:

    • Microwave thermography is a viable tool for breast cancer detection, comparable to infrared thermography.
    • The combination of microwave and infrared thermography enhances diagnostic accuracy.
    • Further research into microwave thermography's medical applications is warranted.
