Characterization of Breast Phantom Models in Coaxial Probe

Breast cancer is a major problem of public health worldwide. The main tool in reducing the death rate from this disease is early diagnosis. Despite the widespread use of mammography, it has some disadvantages in its use as direct patient exposure to ionizing radiation; the similarity in density between tumor and the normal tissues; and low reproducibility in highdensity breasts. The positron breast microwave (MWT) is a very promising alternative to help diagnose breast cancer. This tomography technique has some advantages, greater ease in early diagnosis and difficult location, less exposure of the patient; lower cost; and greater comfort to the patient. It is necessary for the production of phantoms with similar characteristics to human tissue, for the use of MWT in breasts. This work has as main objective the development of a specific breast phantom tomography in microwave and characterization through simulations and measurements in open coaxial probe. The simulation results (using HFSS software) and experimental measurements of phantoms in coaxial probe were consistent with the literature. Given the results, it is expected that the characterization of the research phantoms contributes positively to the consolidation of MWT.
