Abstract
Microwave mammography is being developed as a new examination method for breast cancer. Evaluation of device performance is necessary in the development process of medical devices. However, experiments using the human body or animals tend to be avoided because of the ethical issues involved. An electromagnetic phantom that simulates the permittivity and conductivity of a living body is useful for this purpose. In this study, we aimed to develop a fat-equivalent phantom at 1-15 GHz, which is expected to be used in microwave mammography, and which accounts for a high percentage of the breast. As a result, the relative permittivity and conductivity agreed with the target values with an average error rate of 6.75% and 18.2%, respectively. In addition, the usable temperature range of the prototype phantom was also investigated.
