Effectiveness of Microwave Technique in Early Detection of Breast Abnormalities
In this paper, a breast phantom of CIRS Model 010A contains various known masses and sizes is studied. A
measurement of S11 signals is taken at few locations on a breast surface using an open-ended coaxial probe. The obtained
signals permit the extraction of the dielectric property of the masses. The result has shown that the smallest size detected
through this probe is approximately 0.20 mm, small enough to be detected at early stage breast abnormality growth. This
method undoubtedly recognizes the presence and location of possible abnormalities such as benign and malignant tissues.
Although the model does not contain malignant tissues, this study demonstrates the viability of detecting small breast tumors
using this approach.
