Abstract
Microwave Imaging (MWI) has been explored as
an alternative to conventional breast tumor screening methods.
It is acknowledged that benign and malignant tumors can be
distinguishable by their architectural features: benign tumors
are often round with well-defined margin, while malignant
tumors have an ill-defined margin and are micro-lobulated or
spiculated. We present a MWI-based systematic analysis of
malignant and benign breast tumors of different sizes, to
evaluate if its characteristics allow differentiating the images.
To this end, we performed measurements on a dry MW setup,
using a slot-based antenna in the 2-5 GHz frequency range to
scan an anthropomorphic breast phantom. We placed inside
eight malignant and benign tumors with 3, 4, …10 mm average
radius, one at a time. This study shows that both types of
tumors can be detected, but not distinguishable only via MWI.
Smaller tumors become harder to detect, the 3 mm tumor
being unreliably caught.
