Abstract
Tumor cancer in the human body usually has a different metabolism and thermal properties from the healthy tissue, causing the region affected by cancer to have a higher temperature than the tissue surrounding. In the thermal impedance method heat flux and surface temperature were measured by an HFS - 3 heat flux transducer assembly and a K-type temperature sensor to acquire temperature and heat flux data that can be used to obtain the thermal impedance. This technique also has the advantages of being non-invasive, not causing discomfort to the patient and not emitting radiation. In this work, an inclusion made of PLA was detected in a breast phantom model, which mimics the model of a breast, using thermal impedance method. Tests were performed with an inclusion with internal heat generation, to simulate malignant abnormalities in the tissue, and the external heating of the model. These results are compared to the model without the inclusion (baseline) for analysis of this effect. The thermal impedance values were compared statically using the RMSD damage metric, which were able to show if the inclusion was detect.
