Abstract
This work proposes to study the way in which the penetration of a heating applied on a breast skin surface, aiming show the influence of tumor thermal behavior in infrared thermography analyzes. COMSOL MULTIPHYSICS was used for computational simulations, of a 2D anatomical breast model, whith properties from skin, fat, lymph node, milk lobule and milk duct. Analyses were developed considering how occurs the heat propagation on the breast tissues, in regions with most inclusions presence, as a ductal carcinoma in situ and invasive, and also Lobular carcinoma invasive. The behavior of a constant and periodic heating was analyzed and compared, considering several time intervals. Results indicate that a periodic heating offers greater thermal comfort during thermographic exams, because the surface termperatures are lower than the constant heating. Increases in the time of skin heating increases its thermal penetration region, improving deep tumor detection capability.
