20.500.12556/DKUM-95869 Numerical modeling of non-Fourier bioheat transfer in multilayer biological tissue using BEM to simulate dynamic thermography in skin tumor diagnostics This paper presents a novel approach for modeling non-Fourier dual-phase-lag bioheat transfer in multilayer biological tissue, aimed at simulating dynamic thermography for the early detection of skin tumors at Clark II and IV stages. The proposed algorithm, based on the boundary element method, enables the assignment of distinct thermophysical properties and non-Fourier relaxation time parameters to each tissue layer, thereby enhancing the realism of bioheat transfer modeling. Results show that accounting for non-Fourier effects significantly impacts the transient thermal contrast between tumor and healthy skin, particularly in Clark IV tumors and at higher relaxation times. These findings support the development of more accurate and physiologically realistic models of heat transfer in complex biological structures, and advance the application of dynamic thermography in early skin tumor detection and the diagnosis of other dermatological conditions. numerical modeling non-Fourier heat transfer bioheat transfer dual-phase-lag model boundary element method dynamic thermography numerično modeliranje prenos toplote brez Fourierjevega načina bio-prenos toplote model z dvojnim faznim zamikom metoda robnih elementov dinamična termografija true false true Elsevier Angleški jezik Slovenski jezik https://www.sciencedirect.com/science/article/pii/S0955799725002966?via%3Dihub Članek v reviji 2025-11-03 14:09:17 2025-11-03 14:09:17 2025-11-04 03:34:50 0000-00-00 00:00:00 2025 0 0 str. 1-10, Vol. 179, [article. no.] 106408 Part A Oct. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-02-11 2025-07-23 2025-08-14 519.6:536.2 250838531 10.1016/j.enganabound.2025.106408 1873-197X https://www.sciencedirect.com/science/article/pii/S0955799725002966?via%3Dihub 1 4e4e0bfe-b8b6-11f0-b13b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200356 1-s2.0-S0955799725002966-main.pdf 1-s2.0-S0955799725002966-main.pdf 1 8BBE7A2BC81B5F5EB9B501CA27461282 e746c6d597b4f7edf24498d901d5cf36aca39890c30483071d84317fbc3c7b42 31b1bab5-b8b7-11f0-b13b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=200357 Fakulteta za strojništvo 0 0 0
