Time-domain microwave breast cancer detection: extensive system testing with phantoms

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Microwave Engineering

Background:

• Early breast cancer detection is crucial for successful treatment.
• Current imaging modalities include mammography, ultrasound, and MRI.
• A complementary detection technique is needed to improve early diagnosis.

Purpose of the Study:

• To develop and test a time-domain microwave system for detecting breast cancer.
• To explore the feasibility of using microwave scattering for malignancy detection.
• To establish a foundation for a home-use system for periodic breast tissue monitoring.

Main Methods:

• Transmitting microwave pulses into breast phantoms and recording scattered signals.
• Utilizing the dielectric contrast between healthy and malignant breast tissues.
• Testing with homogeneous and complex phantoms mimicking breast tissues, including skin, fat, glandular structures, and tumors.
• Optimizing the system through various antenna arrangements, tumor sizes, and locations.

Main Results:

• Demonstrated the feasibility and performance of the time-domain microwave breast cancer detection system.
• Identified specific antenna arrangements that enhance tumor detection.
• Showcased the system's capability to detect malignancies based on microwave scattering properties.

Conclusions:

• The time-domain microwave system shows promise as a complementary tool for early breast cancer detection.
• The technology has the potential for non-invasive, periodic monitoring of breast tissue changes.
• Further development could lead to a home-use device for proactive breast health management.
