Millimeter-wave thermography--application to breast cancer
The Journal of Microwave Power
|June 1, 1979
Summary
Millimeter wave scanners show potential for breast cancer detection, correlating well with clinical findings for medium-depth tumors. Further research with more patients and lower frequencies is recommended.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Oncology
Background:
- Thermography is a non-invasive imaging technique used in breast cancer diagnostics.
- Millimeter wave (MMW) imaging offers potential advantages in detecting subsurface structures due to its penetration capabilities.
Observation:
- Thermographic studies were conducted on 14 breast carcinoma patients using 30 and 68 GHz millimeter wave scanners.
- Comparisons were made with infrared thermograms, mammography, and clinical data.
Findings:
- A slight correlation was noted between millimeter wave and infrared thermograms, suggesting depth-sensing ability.
- Millimeter wave imaging showed good correlation with mammographic and clinical findings, particularly for tumors with medium subcutaneous depth.
Implications:
- These preliminary findings highlight the potential of millimeter wave thermography for breast cancer assessment.
- Further studies with larger patient cohorts, lower sensing frequencies, and phantom models are warranted to validate these results.
