Abstract
Breast cancer is the type of cancer that mostly affects women in Brazil, presenting 29.5% of new cases each year. New breast cancer detection methods are being developed to overcome the difficulties encountered in existing methods such as radiation emission and possible patient discomfort. This study aims to evaluate the influence of the depth of the inclusion in the detection using thermal impedance method. In addition to analyze the most suitable external heating location: localized or general in the surface. A silicone model filled with commercial gel was used to simulate the tissue and the adipose tissue. The heat flux and the superficial temperature were acquired in the model and it was possible to evaluate its thermal impedance. Besides that, RMSD damage metrics were calculated between the baseline (tests without inclusions, only with external heat generation) and the model with the inclusion of 10 mm to verify the inclusions. Thus, it was concluded that the thermal impedance method was able to identify the inclusion of 10 mm in all the depths tested when the localized external heatin was applied on the model.
