Complex Dielectric Coefficient of Breast Phantom Prepared for Breast Cancer Detection

Microwave measurement techniques attract attention due to its practical solutions in breast cancer imaging. Early detection of cancer is the purpose of these imaging studies. For these imaging processes, phantoms which re ect the properties of the area to be imaged are produced. The produced homogeneous phantoms are imaged by stepper frequency of radar technology, as the narrow bands are used for heterogeneous mixtures. Phantoms are used since 70's until today. Di erent methods are experimented for producing phantoms of tissue, muscle, fat, skin, etc. Iron powder, polymer materials, various oils and gelatins used today are the materials used for producing the phantoms. In this study, phantom breast imaging is aimed. Phantoms breast and breast tumor samples are created. For phantoms and tumor samples, re ection and transmittion measurements are done with Network Analyzer in X-Band (8.2 12.4 GHz). Complex permittivity is calculated with Agilent 85071 Material Measurement Software Fast Method (NIST iterative method). It was considered breast phantom with tumor model for 3D imagine at 2 3.5 GHz frequency range.
