Abstrakt: Breast cancer appears to be the most common disease among women in the world, and cancer is the first cause of death among women. Microwave imaging systems have been considered as a new more harmless technique for breast cancer detection based on dielectric contrast between healthy and cancerous tissues. In order to develop microwave imaging systems and to test the performance of the developed systems before they are used in clinical tests, it is extremely important to test these systems on phantoms that can mimic tissues in terms of electrical properties. The aim of this project is that the developed breast phantoms are suitable for the real breast structure in terms of dielectric & mechanical properties. Considering such situations, acrylic acid was used as monomer during the preparation of the gel phantom. N,N'-Methylenebisacrylamide (BAAm) as used as crosslinker and potassium persulfate (KPS) as initiator in certain ratio. After synthesis, gel phantoms were purified in different solvents. After the purification and drying procedure, synthesized gels were swelled in distilled water (DW) for 10 days. The swelling ratios of the gels were calculated and their dielectric properties were examined. It is observed that, the relative permittivities of the gels were close to the relative permittivity of DW. [ABSTRACT FROM AUTHOR]
