Summary
This study introduces a novel microwave imaging system for early breast cancer detection. The system utilizes a compact Artificial Magnetic Conductor (AMC) antenna array to non-invasively identify tumors, significantly improving survival rates.
Area of Science:
- Biomedical Engineering
- Electromagnetics
- Medical Imaging
Background:
- Breast cancer is a leading global malignancy in women, with early detection crucial for high survival rates.
- Current detection methods may have limitations in non-invasiveness or early-stage sensitivity.
- Gene mutations driving irregular cellular growth necessitate advanced diagnostic tools.
Purpose of the Study:
- To develop and validate a microwave imaging technique for non-invasive, early-stage breast cancer detection.
- To propose a low-cost, compact antenna array with Artificial Magnetic Conductor (AMC) for enhanced performance.
- To assess the efficacy of the proposed system in detecting tumors within a breast phantom.
Main Methods:
- Design and fabrication of a compact antenna array (37.2 x 37.2 mm) incorporating an Artificial Magnetic Conductor (AMC) metamaterial.
- Antenna characterization including gain measurements (simulated and measured) at 8.48 GHz.
- Experimental validation of antenna operational efficiency and fidelity factors in various configurations.
- Application of the antenna as a transceiver in numerical simulations using a breast phantom with five distinct cases for tumor detection.
Main Results:
- The AMC enhances frequency selectivity at 8.48 GHz, achieving maximum gains of 9.35 dBi (simulated) and 10.51 dBi (measured).
- Fabricated antenna performance validated simulated findings, demonstrating operational efficiency.
- Fidelity factors were analyzed in face-to-face (FtF) and side-by-side (SbS) scenarios.
- Numerical simulations showed the system's capability for cancer cell detection in a modeled breast phantom.
Conclusions:
- The proposed low-cost microwave imaging system with an AMC antenna array shows promise for non-invasive, early-stage breast cancer detection.
- The validated antenna design and simulation results support the advancement of breast cancer diagnostic methodologies.
- This research contributes to developing more effective tools for improving patient survival rates through early tumor identification.
