A Computational Study on the Role of Parameters for Identification of Thyroid Nodules by Infrared Images (and Comparison with Real Data)

Abstract: According to experts and medical literature, healthy thyroids and thyroids containing benign nodules tend to be less inflamed and less active than those with malignant nodules. It seems to be a consensus that malignant nodules have more blood veins and more blood circulation. This may be related to the maintenance of the nodule’s heat at a higher level compared with neighboring tissues. If the internal heat modifies the skin radiation, then it could be detected by infrared sensors. The goal of this work is the… Show more

“…The simulated neck comprises skin, fat, muscle, thyroid, and an elliptic nodule within the thyroid lobe (Figure 1). The thickness of the different anatomical regions is in agreement with previous studies [31,34,35]. Specifically, we set a thickness of 1 mm for the skin, 6 mm for the fat region, 30 mm for the muscle, and 20 mm for the thyroid.…”

“…where k ref is the reference thermal conductivity of the tissue, r i = 0.0013 is a parameter that approximates the temperature dependence of k as in [36], T is the temperature, calculated during the simulation, and T ref = 37 • C is the body temperature. Table 2 lists the physical parameters considered for the RF electrode in agreement with the available literature [23,31]. Relative permittivity ε r (-) 1 1…”
