|March 3, 2025
Summary
This study introduces a new microwave imaging system for breast cancer detection. The system accurately images breast tissue and can detect small inclusions, showing promise for clinical use.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Electromagnetics
Background:
- Microwave imaging shows potential for breast cancer detection and monitoring.
- Previous systems estimated average breast permittivity.
- Development of a detailed breast imaging system was motivated by prior encouraging results.
Purpose of the Study:
- To assess the performance of a next-generation microwave imaging system.
- To demonstrate human subject scans correlating with clinical information.
Main Methods:
- Scans of homogeneous and inclusion-containing phantoms were collected using a novel imaging system.
- System accuracy, detection, and localization capabilities were assessed.
- A pilot study involved scanning healthy volunteers with prior mammograms.
Main Results:
- Reconstructed average permittivity in phantoms showed less than 10% error.
- The system successfully detected inclusions of 1 cm diameter and larger.
- Microwave images of healthy volunteers were successfully acquired, demonstrating feasibility.
Conclusions:
- The novel high-resolution microwave transmission imaging system is effective for breast imaging.
- The system, with its fast reconstruction algorithm, can detect 1 cm inclusions.
- The imaging system is suitable for further investigation in human subjects.
