Microwave imaging of biological tissue phantom in different frequency ranges

In the present study the microwave images for the breast tissue phantom in different frequency ranges were obtained. The phantom was made of lard imitating fat breast tissue and dielectrically contrast inclusions. Experimental data were gathered by using the installation consisted of a vector network analyzer, two linear drives, a single transceiving antenna, flexible armored antenna feeders, a microcontroller board, and a computer. Recorded by the vector network analyzer scattered electromagnetic field parameters were further processed utilizing an algorithm written in Python Programming Language to reconstruct microwave image of the inner dielectric inhomogeneities of the phantom.
