Area of Science:

  • Medical Imaging
  • Oncology
  • Biomedical Engineering

Background:

  • Breast cancer is a significant global health concern, particularly for women.
  • Mammography has limitations, especially in younger women with dense breasts, driving the need for alternative screening methods.
  • Early detection is crucial for improving breast cancer patient outcomes.

Purpose of the Study:

  • To evaluate the feasibility of using thermal imaging as a non-invasive tool for breast cancer detection.
  • To assess the efficacy of infrared imaging in identifying malignant breast conditions.
  • To explore automated classification of breast images using texture features and machine learning.

Main Methods:

  • Utilized 50 infrared (IR) breast images (25 normal, 25 cancerous) from Singapore General Hospital.
  • Extracted texture features using co-occurrence matrix and run length matrix.
  • Employed a Support Vector Machine (SVM) classifier for automated classification of normal and malignant breast conditions.

Main Results:

  • The proposed thermal imaging system achieved an overall accuracy of 88.10%.
  • Sensitivity for detecting cancerous conditions was 85.71%.
  • Specificity in identifying normal breast conditions was 90.48%.

Conclusions:

  • Thermal imaging demonstrates potential as a non-invasive screening and diagnostic tool for breast cancer.
  • The combination of IR imaging, texture feature extraction, and SVM classification shows promising results for automated breast cancer detection.
  • Further research is warranted to validate these findings in larger cohorts and diverse populations.
