A clinical prototype for active microwave imaging of the breast
Despite its recognized value in detecting and characterizing breast disease, X-ray mammography has important limitations that motivate the quest for alternatives to augment the diagnostic tools that… Expand
Enhancing breast tumor detection with near-field imaging
This article outlines the main features of active, passive, and hybrid systems under investigation for breast cancer detection. Our main focus is on active microwave systems, in particular microwave… Expand
Initial clinical experience with microwave breast imaging in women with normal mammography.
RATIONALE AND OBJECTIVES We have developed a microwave tomography system for experimental breast imaging. MATERIALS AND METHODS In this article, we illustrate a strategy for optimizing the coupling… Expand

We have performed a series of experiments, which demonstrate the effect of open-ended coaxial diameter on the depth of penetration. We used a two-layer configuration of a liquid and movable… Expand
Electromagnetic breast imaging: results of a pilot study in women with abnormal mammograms.
PURPOSE To prospectively assess quantitatively the inherent contrast of electromagnetic (EM) properties that can be imaged by using available technology in women with abnormal findings at… Expand
Microwaves for breast cancer detection
Microwave imaging for medical applications has been of interest for many years. Microwave images are maps of the electrical property distributions in the body. The electrical properties of various… Expand
The correlation of in vivo and ex vivo tissue dielectric properties to validate electromagnetic breast imaging: initial clinical experience.

- Physiological measurement
- 1 June 2009
Electromagnetic (EM) breast imaging provides low-cost, safe and potentially a more specific modality for cancer detection than conventional imaging systems. A primary difficulty in validating these… Expand
Electromagnetic breast imaging: average tissue property values in women with negative clinical findings.
Representative data are provided for three electromagnetic breast imaging techniques-near-infrared spectroscopy, electrical impedance spectroscopy, and microwave imaging spectroscopy-to serve as… Expand
